Firefox 57 release overview

Mozilla plans to release Firefox 57.0 to the stable channel on November 14, 2017. The new version of the web browser is a major release as it introduces big changes to the browser's performance, interface, and add-on compatibility.

In short: the new version of Firefox is a lot faster than previous versions, replaces the Australis interface introduced in Firefox 29 with the new Photon interface, and drops support for the legacy add-on system to focus on WebExtensions.

Executive Summary

  1. Firefox 57.0 comes with a design refresh called Photon.
  2. Legacy add-ons and themes are not compatible anymore.
  3. Performance improvements thanks to Project Quantum.. Mozilla states that Firefox 57 is two times as fast as Firefox 52.0.

Firefox 57.0 download and update

Firefox 57.0 will be released on November 14, 2017 to the browser's stable channel. Existing Firefox users will have the browser updated automatically on the day, provided that automatic updates is enabled.

Firefox users can run manual checks for updates in the browser with a click on Menu > Help > About Firefox.

The release is already on Mozilla's FTP server, but it is best to wait for the public release announcement by Mozilla. Mozilla will update the download links as well on November 14.

Firefox 57.0 Changes

Firefox 57 is probably the most important release for Mozilla in a long, long time. The organization removed the old add-ons system from Firefox, refreshed the interface, and integrated some parts of Project Quantum in the browser.

Photon design

firefox 57 new tab page

Firefox 57.0 comes with a modified interface, the first major refresh of Firefox's design since the release of the controversial Australis interface in Firefox 29.0.

Photon is more than just an interface overhaul however as it is part of the Mozilla Quantum project. This means that Photon is not just a new paint for Firefox, but something deeper that took factors such as speed and responsiveness into account.

As far as the interface is concerned, Firefox 57.0 introduces changes to the New Tab page, the Firefox menu, themes, and customization options.

Firefox's theme has changed; if you used a previous version of the browser you will immediately notice the changes. Version 57.0 of the browser comes with a light and dark theme that you can switch between, and options to change the theme's density to touch or compact modes. Compact uses a little bit less of space, touch is optimized for devices with touch capabilities.

The Firefox menu is still at its default location, but it is not made up of icons anymore but of text links (with icons instead). The menu is fixed, meaning that you cannot add or remove items from it anymore.

Customize options are still provided though as you can see on the screenshots above. You can still drag and drop many interface elements around, or remove them entirely from the browser UI. New items can be placed on the main toolbar or a new ">>" menu designed for items that you don't want placed on the toolbar but in reach anyway.

When you navigate to a site you will notice the new "..." menu that is placed inside the address bar. This is the new Page Actions menu that lists options to interact with the page directly.

firefox 57 page actions

You find options to bookmark the page, or save it to pocket, and options to copy or email the link, send the tab to a connected device, or take a screenshot there.

Mozilla added dupes of the first two options inside the address bar as well. A right-click on the entry, e.g. "save page to Pocket" displays options to add or remove the icon from that spot.

The New Tab Page and Start Page of Firefox 57 is based on Activity Stream now. Activity Stream was launched as a Test Pilot experiment before Mozilla implemented the functionality in the browser.

The page features a search, top sites, highlights, Pocket recommendations (only select countries) and snippets that Mozilla displays. Firefox users can customize the New Tab page with a click on the cogwheel icon to display or hide any of the elements (removing all leaves a blank page).

Users who want more control can install the New Tab Override extension by Sören Hentzschel.

Photon is more than just the visuals that you see on the screenshots.Mozilla tweaked animations, icons and many other things to improve the responsiveness of the browser.


The second big change in Firefox 57 is that parts of Firefox's new web engine Quantum are implemented in the browser. Mozilla stated earlier that Quantum made Firefox twice as fast for some operations when compared to the recent Firefox 52.0. That's an impressive gain.

Quantum makes use of technology that modern processors offer. It supports parallelism and other features, and uses these to make Firefox faster.

Quantum CSS, also known as Stylo, is the first major Quantum component that Mozilla integrated into Firefox.

Without going into too many details, Quantum CSS uses parallel computing and other improvements to make the handling of CSS in Firefox a lot faster.

Mozilla revealed in September that Firefox engineers removed a total of 468 issues related to speed, bottlenecks for instance, in the preceding months.

You can check out this overview on Mozilla Hacks for details on that, and this article on Quantum in general on the same site.

Quantum makes the browser more stable at the same time, as Quantum Compositor was moved to its own process thanks to the previous integration of Electrolysis (multi-process Firefox).

In short: Firefox feels a lot snappier and faster.

Changes to the Firefox add-on system

firefox legacy extensions

Firefox 57 does not support legacy add-ons or themes anymore. Firefox users who ran those in previous versions of the browser will notice that these have been disabled during the update to Firefox 57.

So, if you have updated to Firefox you may notice that some of your add-ons have been disabled, and that is the reason why.

Add-ons and themes that have been disabled are listed under legacy extensions on about:addons. Options to remove them and to use the new "find a replacement" feature are provided.

Read also:  Mozilla reveals plan for themes in Firefox

There is no guarantee that a replacement is available however. The Classic Theme Restorer extension for instance cannot have a replacement as WebExtensions cannot replicate its functionality.

In short: Firefox 57 supports only WebExtensions. Plenty of popular extensions have been ported, but there is an equally large number of popular extensions that have not yet. Some will never be ported for one reason or another (because of developer disinterest, a lack of APIs or because they are abandoned by their developer).

Mozilla plans to support legacy add-ons throughout the lifetime of Firefox ESR 52. The Firefox ESR 59 release won't support legacy add-ons anymore, and Mozilla noted already that there won't be a switch to enable legacy support again.

New Permissions in Preferences

firefox new permissions

You find (some) permission controls in the preference in Firefox 57. You can control location, camera, microphone and notifications directly there.

Load about:preferences#privacy and scroll down to the permissions section. A click on settings displays all sites that requested access to the linked feature, e.g. location. You can remove select websites or all websites from the listing at any time.

There is still some work to be done in this regard though, as controls lack options that Firefox's classic permissions system offered (removed by Mozilla).

Other Firefox 57.0 changes

  • The Share button has been removed in Firefox 57. You can install the Firefox add-on Share Backported to bring it back.
  • The autoscroll feature of Firefox uses asynchronous scrolling in Firefox 57. This should improve the smoothness of the scrolling of this mode.
  • The Linux security sandbox is set to a higher (more restrictive) level in Firefox 57.0. It blocks file system reads and writes on Linux systems. Firefox users on Linux who run into issues after the upgrade to the new version can modify the sandbox level accordingly (see known issues below for instructions).
  • Pressing the middle-mouse button in the content area on Unix systems does not navigate to URLs anymore by default.
  • Support for AMD VP9 hardware video decoder that improves video playback with lower power consumption.
  • Tracking Protection is now available as an option for all sites. It was previously only available for sites in private browsing mode.
  • Firefox 57 ships without visible search bar in the interface. You can enable it under about:preferences#search on new installations. Old installations should not be affected by this.

Firefox 57.0 Issues

Firefox 57.0 has three unresolved issues that may affect users of the browser:

  • Firefox users who operate screen readers are advised to use Firefox ESR until performance issues are resolved.
  • Firefox may crash on Windows and Linux systems with Intel Broadwell-U processors. Mozilla suggests that Windows users make sure the most recent updates are installed, and that Linux users should make sure the distribution package for Intel microcode is installed.
  • Firefox for Windows users who use the browser over Remote Desktop Connections (RDP) may have no audio as it may have been disabled due to security restrictions. Mozilla's support page suggests changing the level of the Firefox sandbox to 2.
    • Load about:config?filter=security.sandbox.content.level in the browser's address bar.
    • Double-click on the preference and set its value to 2.
  • Older versions of the Japanese Input Method Editor ATOK IME may cause crashes, and are disabled because of that on 64-bit versions of Firefox on Windows. Mozilla suggests to upgrade to a newer version or another IME.

Developer Changes

  • Visual refresh of DevTools themes.
  • New and re-designed Console panel (written in React and Reduct), allows  to inspect objects in context now.
  • The rel="preload" attribute has been disabled again.
  • New -screenshot flag for the headless mode of Firefox.
  • resource:// URIs don't leak information anymore.
  • Lots of Quantum CSS, WebExtensions changes. Consult the resource section below for links to the information.
  • Social API is completely removed.
  • Legacy add-ons maximum compatibility is set to 56.*. Developers cannot upload legacy add-ons with a higher maximum compatibility.

Firefox 57.0 for Android

  • Only supports WebExtensions. Legacy add-on support dropped.
  • Features performance improvements for faster page load times and better stability.
  • New Tab page updated.
  • Video decoding shuts down automatically when the playing tab is sent to the background. Will resume automatically when brought back to the foreground. Audio continues to play.
  • Tracking protection outside of private browsing supported.
  • Private mode automatically enabled on compatible keyboards when in private browsing mode.
  • Long URLs can be scrolled now in the address bar.
  • Added wo locale.

    And gone are the legacy add-ons. Hope kicking the users who once recommended them in the butt will help them gain market share.

    It's pretty fast, though.

    • kir67 November 14, 2017 at 7:31 am #

      The users you are talking about have done a very bad job helping them gaining market share.
      Firefox was losing market share constantly.
      The masses want speed. They got some speed improvements in 56 and market share went up.

      And gone is the legacy search bar. Search bar addon

      • 0-0-o-0-0 November 14, 2017 at 11:27 am #

        What are you talking about ? The search bar is still there, you just have to use Customize and drag it...

      • streetfighter November 14, 2017 at 12:00 pm #

        This is not the legacy search bar. You have no idea what you are talking about.
        The search bar is still there, it's just not enabled by default.

      • Ragnar November 16, 2017 at 11:26 am #

        Legacy search bar is as is. If you upgrade from a older version you'll see no change. However on a fresh install I believe it's hidden, but check your settings as you can easely change the look and add it. No need for drag and drop as some said. However the legacy search bar is not needed as the addressbar has the exact same functionality. Cheers!

      • Gary D November 13, 2017 at 7:51 pm #

        I see that all the usual moaners about Firefox are posting. Please stop. Your comments make for very boring reading. Alternatively all the "power" users could start a new fork that will satisfy them.

        Do what I and many others have done and stay with FF52 ESR. I can still use all the Legacy addons.

        I look forward to the usual barrage of negative replys :)))))

        Why don't you switch to IE11, Edge, Chrome, Opera or even Waterfox?
        If you do, you won't need to be negative about FF anymore and get depressed reading blogs about FF and its missing features.

    • Appster November 13, 2017 at 6:16 pm #

      Looks more like Edge with Chrome add-ons. Firefox was all about customization, so not sure if your statement holds.

      • kir67 November 14, 2017 at 7:16 am #

        Firefox was never about customization. That's only in your head.
        If it was about customization it would have these customizations built-in, not through addons.
        Firefox is a FOSS browser fighting for a Web to stay open and interoperable.
        This is what Firefox is about.

      • Appster November 14, 2017 at 9:03 am #

        @kir67: People were not using Firefox for ideological reasons. The vast majority out there doesn‘t give a flying fuck about „FOSS“ or „open web“. Have a look at the Chrome market share today and Internet Explorer market share before that for more info.

        Customization and extensibility were always Firefox‘s main selling points. That‘s why XUL was there in the first place. Original Mozilla created it this way on purpose.

        By the way, even Firefox‘s built-in customization was much stronger than that of the competitors, in the past.

        So no, it‘s not „only in my head“. Have fun with FireChrome 0.1...

      • kir67 November 14, 2017 at 10:34 am #

        Of course the vast majority out there doesn‘t give a flying fuck about „FOSS“ or „open web“.
        But... the vast majority don't give a fuck about customization and extensibility too.
        If they did, Firefox's market share wouldn't go down and down and down.
        People want speed and they will have it, Firefox's market share already went up after the release of 56.
        Also.. customization and extensibility weren't always Firefox‘s main selling points.
        That happened when it was the only selling point left. It was behind on everything else.

        Quantum is the future, Appster. Better get ready for it.

        All your nay-saying isn't going to turn back the clock, son

      • Simple Shredder November 15, 2017 at 1:29 pm #

        @Gary D

        You're comments are noted, but quickly dismissed and forgotten, but before they are, here is a tidbit.

        Everyone has the same right as you to voice their concerns, likes and dislikes, if this upsets or bores you, the wider internet is just one click away.

        As for your other comment that power-users should make their own fork. It takes more than power users wanting something to happen, not every power-user can code and it takes real hardcore developers, and not just one or two; you need a real team of developers and other contributors behind such projects. They need to understand the intricacies of the underlying technologies and security to make any such project come to fruition, not to mention the amount of resources required aside from humans.

        If you ever had to develop, maintain and support anything in your life you know this isn't a straight forward proposition as you make it sound. But its easy to spew some hateful crap without any real consideration but your ego.

        @Appster, indeed, but you forget that its very likely that the majority of users dont really get that involved, just because they use an addon or three, which is the vast majority of users, they often forget that the actual power of Firefox lies elsewhere which has been amputated and mangled and will die forever.
        So trying to explain this reality to one addon or three users like Gary and Nir67, is like trying to convince flat earthers the planet is not flat.

        What is astounding for me is that the ignorance is such that these people commenting believe you need to sacrifice power for speed, YOU DONT, its just sad that Mozilla and the developing community dont actually make better standards and extend webextensions like they claim they do.

    Been using Firefox 57 betas for some time on my order laptop which struggled on more demanding sites, i have to say it's the most responsive browser i have ever used.

    If firefox retains it's configurability via about:config / user.js it will remain my main browser; nothing can beat that.
    Regarding web extensions and removal of classic extensions i wont miss anything critical, i hope noscript makes it to AMO asap.

  5. Ficho November 13, 2017 at 6:31 pm #

    Two bugs :
    - It doesn't start with maximized window.
    - It doesn't remember per site zoom settings.

    • Cloudman November 13, 2017 at 6:39 pm #

      I don't have those bugs.

      • Ficho November 13, 2017 at 7:06 pm #

        Both problems solved by disabling ' privacy.resistFingerprinting '.

    • G November 13, 2017 at 6:54 pm #

      Both of those issues can be caused by having the "privacy.resistFingerprinting" pref set to true. Maybe this is the case?

      • Ficho November 13, 2017 at 7:13 pm #

        Thanks. I already found solution online.
        Is ' privacy.resistFingerprinting ' the same as ' canvas.poisondata ' in Pale Moon ?

      • Richard Allen November 14, 2017 at 6:59 am #

        No, they are two different things. "privacy.resistFingerprinting" is used for many diferent things but it does not prevent canvas fingerprinting. I think FFv58+ will have the ability to prevent canvas fingerprinting on a per site basis. If you want more info, copy - privacy.resistFingerprinting - and go to then use CTRL+F (find in page) and then CTR+V. I think the third match has the most info.

    • FoxNoMore November 16, 2017 at 12:00 pm #

      Works fine with mine zoom and max window, its all the other shit that bothers me like tabs on top and address bar unmovable its a really crap layout and as far as speed is concerned its no frigging different, people creaming their pants about speed need to get a life. This is just a version of MS Edge with a different badge total BS.

      • Jody Thornton November 17, 2017 at 3:13 am #


        Tabs were on top before too - don't count CTR because that just came to the rescue after Australis (you Firefox fanatics hated that too - so did I) And you can still use usrChrome code to get tabs below the address bar. And so what, we like the speed improvements? Don't say i'm juizzing myself over that. How friggin rude.

        Firefox was about powerful add-ons and built in customization features, All the ones who hate that with passion are deluded leftist fanatics who feel their safe space invaded because of features they do not understand.

        Go back to North Korea you communist cancer! Conservative features should stay inside the browser. You mentally deranged liberals destroy everything which surpasses your limited mental capacity!

        Leftists destroy progress with their opinion that only they have the right to deliver diversity and that only they know what diversity actually is.

        Conservative geeks/power users diversity:
        Freedom for everyone, simple and advanced functions inside a product - functionality=no bloat; That user group is willing to explore, learn new complex options and use them for their own benefit

        Leftist diversity:
        Only simplicity, minimalism, no complex features as require time and the will to learn and to understand and are therefor bloat. Also taking care for the social aspect of product development - that only the most basic feature set ensures that dumb users do not feel demotivated or angered by the features they do not understand = Safe space; That user group is lazy, racist, discriminating and unwilling to explore or learn new more time consuming functions

    I started using firefox when it was released. I have worked with all browsers. Firefox always stayed my number 1 browser. Never ever I switched to another.

    I have to say that i am not happy with that legacy addons are disabled. I choose firefox because it's limitless with customisation. Now it's not like that anymore.

    We can't adjust the menu, we always could. Dont know why.

    • Appster November 13, 2017 at 7:07 pm #

      That's because Mozilla knows what it is good for you, and wants to preserve its UI branding. And no, that's not a joke, sadly. I recommend switching to Firefox 52 ESR (note that direct downgrade is impossible due to changed profile structure since Firefox 55, Firefox 52 ESR will need a new profile) or Waterfox (will import current profile) if you are into add-ons.

  10. daguil jein November 13, 2017 at 7:16 pm #


    Any chance you could write an article entitled "Update to FF57 for User.js Newbies"

    Background: I switched from Chrome to FF and implemented user.js about two months ago. I left the user.js file as-is from github in the Profiles/[profile_id] folder with a couple of exceptions in the Profiles/[profile_id]/preferences folder. (Which I see is going out of style with FF58 & will need to get pasted into the bottom of the user.js file itself.)

    Reason for the request: I updated from FF55 to FF56 on the day of release without considering user.js. Firefox started behaving strangely. Turns out one of preference override settings was causing an error. Now I'm paranoid about updating from FF56 to FF57. I don't understand the how the upgrade will interact with or affect my user.js implementation.

    --> First: should I hold off on the update to FF57 until Pants puts out a v57 user.js file? Right now the github releases shows v56 at the top of the page.

    --> Can you show how to go about pulling a new version of user.js from github? Seems like the only option is to download all project files as zip file, then extract the user.js file. Am I getting that right?

    --> Can you show what settings need to get commented out and then updated to default in about:config? I am VERY thankful to Pants for User.js AND for all the documentation. I get the idea of doing a compar/diff, then updating the settings that need to get changed to their defaults. But I have no idea how to put that into practice & could use an example. I have read Pant's wiki 1.5 "Keeping up to date."

    Thanks again for your site, and to Pants for creating & maintaining user.js & wiki.

      The user.js update will be out soon I presume. I publish an article about it as soon as Pants gives the word.

      • Pants November 13, 2017 at 7:57 pm #

        There's not much change - ignoring the deprecated and items to with disabling some prefs due to resistFingerprinting changes, and ignoring a couple of personal items of interest - maybe 6 or 7 items in total

        These two telemetry pings for starters:

        Here's the issue for 57 changes:

      • Anonymous November 13, 2017 at 8:03 pm #

        Reading this above "Both of those issues can be caused by having the "privacy.resistFingerprinting" pref set to true", I wish Pants courage.

      • daguil jein November 13, 2017 at 8:32 pm #

        Awesome. Seeing all the work you do on this... I sincerely appreciate it.

        From the link you provided to the Github issue for the switch from 56 to 57: Whenever a line has "Prev" at the end, i.e.:
        changed in v57.0:
        pref("browser.storageManager.enabled", true); // prev: false 2706 1399398
        ...does that mean that the setting will need to be reset to default in about:config? I mean, after I update user.js to v57, then should I comment out that line, restart FF, reset to default in about:config, then un-comment out the line in user.js? this procedure only required in the rare case of a setting value changing from ["True","False"] to [0,1] or the set of allowable values has changed from [0,1,2,3] to [0,1] and I've got it set to "2" (no longer valid) for the setting in question?

        Sorry if I'm making this complicated than it is.

      • Pants November 13, 2017 at 10:28 pm #

        the "// prev somevalue" is for changed default values. Earthlng picks up on all changes - new stuff, stuff that disappeared, and stuff that changes - so three types. That's is all that notation means - showing us what the old value was.

        Each pref we evaluate on it's own and make a decision what to do - eg often it can be something we already had in the js, and FF finally fell into line. eg we're already in the user.js at minimum TLS v 1.2 and Firefox is not, but have been in beta for about 3 versions but at the last second don't go ahead with it. Even if they did, nothing for us to do.

        Almost all the time, where we change a pref value in the user.js due to firefox making "changes", the pref remains "active" (i.e not commented out), so you wouldn't have to do anything. The easiest thing to do is to wait for the changelog issue earthlng writes

        As for keeping up with the changes - if we remove something (which we have done in the past), you would want to reset those, same with deprecated items (although they will not hurt since they no longer do anything), and same if we made something from active to inactive (i,e not commented out to commented out)

        To reset something, you would need to make sure it was commented out in your user,,js and you would need to find the pref in about:config and right click it and reset

        Here's an interesting way of doing things:
        - This is one way to reset every single pref in the ghacks user.js back to default (including those we removed), then restart FF which will apply only the active prefs. i.e all active prefs = applied, all inactive prefs = reset. All in one hit.
        - I'm still in the process of creating those js files which will be stored here:
        - The idea is to provide an overall script of everything eg clear_prefs56_all.js and clear_prefs56_deprecated.js etc, and then in future just create scripts for each release eg "clear_prefs57_release"
        - ^^ clearly not ready yet

    I'm sad and at the same time excited. Sad because I'll lose some of the most useful addons (like Tab Mix Plus), but at least I can look forward to a Firefox overhaul with a lot of improvements and better performance.

    I guess it's time to look for add-on replacements.

  12. anon November 13, 2017 at 7:47 pm #

    It is faster than it used to be, not quite fast enough yet but getting there. But still seems like the WE APIs just aren't ready. I'll be amazed if they don't lose a whole bunch of users when they see their extensions disappear and in some cases there's no WE alternatives.

    • Jody Thornton November 17, 2017 at 2:36 am #

      Sounds like market share went up in v56 already. I'd expect that to improve in v57. It appears they'll gain more than they'll lose. I'll admit I'm a tad surprised by the trend.

      • bob November 17, 2017 at 6:58 pm #

        If I recall, something like 40% of users don't even use addons.

        And I'd imagine out of those that do, most are probably using the type of addons that work with v57 (e.g. an adblocker).

        People that are heavily reliant on legacy addons that muck with the browser internals are a (loud) minority.

      • Jody Thornton November 18, 2017 at 1:51 am #


        I agree. I used to be fussy about all of this. Then I just took a pill. I get Appster's frustration. I don't know what advice to give him. I know what it's like to have an extremely customized work pattern, and have it ruined. I think that's why I stopped being that way, because I've learned nothing is forever set in stone.

        I'm using Quantum at work, where no add-ons are needed. Wow! It's fast.

    I took a look at my add-ons and it seems I gonna stick with esr release for now... I have 18 legacy add-ons that i NEED and it seems that there is no replacement for them for the time being.
    If Mozilla didn't work on making web extension more versatile as the legacy one, they gonna lose a decent chunk of its market share, and I am afraid that this transition was premature.

    • Putzki November 15, 2017 at 11:03 am #

      Are you sure you need them so badly? I miss some of my add-ons too, but they were more like "nice to have", except one (session manager).

      • Jody Thornton November 17, 2017 at 2:38 am #

        Same here. I'm actually glad that I'm not so reliant on add-ons. I loved FoxE9 for Pale Moon and Firefox (pre-Australis), which gave an IE9 appearance to the GUI. But I love Photon too, so I lucked out there.

  15. kosmos November 13, 2017 at 8:35 pm #

    I want to move away from Chrome, but haven't found the perfect replacement. Used to run Firefox, and then Google created Chrome, which definitely faster than Firefox.

    Over couple of years, I had tried to go back using Firefox several times, but it was definitely slower than Chrome. With Chrome, I only need to restart my browser every few days, but with Firefox, I have to restart it every couple of hours before it becomes very sluggish (Note: I run them on a quite old laptop, so it might have effect).

    Looking forward to the development of Firefox "Quantum", hopefully it can become good enough to replace Chrome.

    • Rush November 15, 2017 at 9:21 am #

      I downloaded FFv57 yesterday and gave it a whir-rel, a couple of hours later, I had two tabs open, was streaming a basketball game on one, and the other reading a sports website, when I noted I could not see my wireless mouse pointer, I usually have task manager on the tool bar and was able to quickly note that, and just FF (the two tabs) was using 1.2 Gigs of my allotted 8 Gigs of ram. I have no viruses, or malware.

      I closed the browser, ran CCleaner and re-opened the browser and it corrected but, I have never seen a browser use that much ram with only two tabs open.

      Waterfox is my main browser, and will continue to use it as such.

      • Rush November 16, 2017 at 12:46 am #

        A new day, tried FFv57 again...a couple of hours of listening to Jazz on youtube...I checked resources...with no overt applications running other than FF browser, one tab..... 1.6 gigs of ram.

        Unless there are other extenuating factors with my machine that is causes just this browser v57 to be a resources hog. I will try to research that end of the problem.

        1.6 UNACCEPTABLE

        v57 may seem faster, but is that just a hologram?

      • Jody Thornton November 17, 2017 at 2:42 am #

        But @Rush, using more RAM to do something shouldn't be an issue anymore. I run Windows 8 and my system usuaes nearly 2 GB of RAM for the OS, Windows Mail, and my browser with eight or so tabs open. Still, with 7 GB of RAM in total, I have lots left. And it runs speedy and stable.

        We're not in the days where XP ran in 512 MB, and Windows 2000 did the same with 64 MB of RAM. More resources do more things in the background to provide a more stable experience.

    I'm aware that using profiles past version 55.0 on ESR will break the browser though I was wondering if it's okay to copy and paste some important things such as bookmarks, sessions, saved passwords and such?

    • Pants November 13, 2017 at 10:38 pm #

      AFAIK the problems lie with places.sqlite due to changes with favicons (they were stored as BLOBs in there, but now use favicons.sqlite due to larger icon sizes allowed etc - and the places.sqlite table has changed, so backporting means it breaks).

      Export your bookmarks. Backup your profile. Then copy over your cookies.sqlite, permissions.sqlite, signons.sqlite, key3.db, cert8.db, formhistory.sqlite. Start FF, import your bookmarks. I THINK you'll be ok with all those. Some extensions you can also do eg stylish.sqlite, Scrapbook folder, FVD Speedial folder etc.

    • Richard Allen November 14, 2017 at 7:10 am #

      This is the list I use:
      content-prefs.sqlite - site specific settings e.g. page zoom
      favicons.sqlite - bookmark favicons
      handlers.json - how to handle different file types
      key3.db - passwords1
      logins.json - passwords2
      permissions.sqlite - website permissions
      persdict.dat - personal dictionary
      places.sqlite - bookmarks, downloaded files, websites visited
      search.json.mozlz4 - user-installed search engines

      cert8.db - is for security certificates and only needed if you've added any personal ones, I've never used any personal certificates. If I'm not mistaken, when deleting cert8.db, it will remove any intermediate certificates and the cert.db will be recreated next browser startup, it's size will be smaller, sometimes significantly so. I've done that many times without any ill effects. that I've ever noticed.

  17. MOYcano November 13, 2017 at 9:36 pm #

    I've been using Quantum Beta for about three weeks. I didn't note the speed change; maybe it is because I have very good PCs; or maybe, the previous version already was quite fast IMO. On android, on the other hand, Chrome is way faster than Firefox but according to the change-log for the latest beta the changes seem to be mostly cosmetic? See it yourself:
    "Updated interface, including a revamped new tab page that includes top visited sites, and recommendations from Pocket (in the US and Canada); Automatically enable private mode on compatible keyboards during private browsing; Long URLs in the URL bar are now scrollable; Added Wolof locale"

    FF57 is going to be soon, but no all required APIs for Session Manager. Shame on Mozilla.

    So the day I have been dreading for over a year is almost upon us. Thanks for the warning, I double checked to make sure auto updates was off. I'm going to sit this out and wait several months to see if any other reason to upgrade appears other than vague speed promises I don't care about. Extensions are the reason I started using Firefox years and years ago. Mozilla just decided to rip its soul out.

    • aiden November 14, 2017 at 8:46 am #

      right, so the world should stop because someone and progress should be halted because third parties don't want to update their extensions. Imagine where we would be today if progress was stopped because of third parties who mostly have packed a sad and refused to do updates because their knickers got in a twist.

    Might anyone point me to a tutorial to install ESR with present profile, separate from regular FF with said profile ? Want to be able to use both with no interference. Also, ESR 52, or some older version ?

    I have searched for this but did not find anything self-contained, recent and simple.

    (Pet rant : profile management in FF is horrible. I had to write my own user manual for this, and I still can't make sense of what I wrote myself to myself. I don't suppose this has changed in Quantum.)

        Fantastic resource, thank you. Even if not using Ghacks User.js. Much more polished than other pages I've read on the subject. There should be a permanent link to it here...

        I've now installed ESR with my old profile, and I feel like I'm breathing again. Yellow bookmark folders are back, the bookmark panel can be opened with a single click, less add-ons are broken... (and that's before making the jump to Quantum).

      • Anonymous November 14, 2017 at 8:26 am #

        My pleasure. My personal choice was for "FirefoxPortable2ndProfile" with "AllowMultipleInstances=true" in "FirefoxPortable.ini" added beside "FirefoxPortable.exe". It worked perfectly, thanks Pants. However I tried with FF57, this solution don't work.

      • Pants November 15, 2017 at 9:56 am #

        Don't use the same profile for ESR 52.x and FF55+ - there are differences that make the 55+ version backwards incompatible, and attempting to do so will corrupt the profile for BOTH versions

        PS: The same is going to happen with FF58 I think (can't find the link now) - i.e FF58+ will be backwards incompatible - or it might be 59 ... just be careful, and always back up your profile(s)

      • Clairvaux November 15, 2017 at 2:19 pm #

        Thanks, Pants. I have indeed set up different profiles for each FF executable.

        Is it still necessary to use the -no-remote switch, even though I don't start several Firefoxes concurrently ? This is annoying, because links can't be clicked anymore in other programs (they insist for another instance of FF to open).

        Also, is it normal that I have a single Profile Manager for both FF executables ? I'd rather have separate ones for each, if at all possible. That would eliminate the risk of cross-profile use.

        P.S: I re-read your comment, and realised I might already have made a mistake. I copied my post-55, Release 56 profile to use with ESR 52, and am now using separate profiles for Release 56 and ESR 52.

        However, this might still be wrong, since the copied 56 profile would be incompatible with ESR 52 ? Correct ?

  22. Maou November 14, 2017 at 3:29 am #

    It's a great release indeed, even my oldest Sandy Bridge computer runs FF57 like a champ!
    But since I'm on beta channel in my main machine, it just updated to FF58, which I dare to say it's even fast.

    Hats off to Martin for writing such comprehensive list of changes, it's way more interesting to read than say "Firefox release notes".

    • rip.firefox November 14, 2017 at 1:09 pm #


      My complex needs are more towards customization rather than specific addons and this has been ripped out.

      For instance, usability wise I think its faster to have tabs on the bottom rather than on the top, you're browsing around in a webpage and to change to another tab you need to traverse the bookmark toolbar (I have it enabled to access many used sites on a pinch) then you need to get past the search bar to reach the tabs.

      I find it easier to go up and tabs are the first thing, then the bookmarks toolbar then the address bar/search bar, this is more efficient and faster.

      I cant do that anymore come 57, so the seconds earned by the speed increases are somewhat lost in this convoluted design.

      The use of /* AGENT_SHEET */ with Stylus addon or the new Stylish addon is also gone, because webextensions killed that, so css wise, cant customize other useful portions of the browser to my preference and am forced to use whatever is provided which is ugly in comparison.

      Im all for better and more efficient everything, improved security like canvas blocking is a plus,, Ide say that most improvements are a plus overall, but those two losses for me are what gave Firefox the edge over the competition.

      The ability to take the default browser and make it your own to suit your work-flow and style and simplicity are gone maybe for good. This is sad and its sad that neither Waterfox nor Palemoon will fill that gap either, because using either is like going backwards, sure you gain back the ability to do those things, but you also lost important changes that improved other areas.

      Firefox is no longer the browser for everyone, its just more of the same, because lest face it, just because the tech is different, the crucial stuff for users of all types is not, and thats has nothing to do with the legacy addons, NOTHING.

  27. Richard Allen November 14, 2017 at 7:04 am #

    Just did a clean install going from v56 to v57 and the performance is excellent. No other mainstream browser (non-FF) comes close to what can be done with css in the UI or has the resources available (images) to do so. Anti-fingerprinting, SSL/TLS capabilities, network configuration, scrolling performance, 60FPs video playback (zero dropped frames 1080p 60fps, chromium browsers always have a few, on my hardware) and a crapton of privacy and security settings are available and easily exceed anything offered by a chromium browser.

    Layout.display-list.retain is now enabled by default in Nightly v59. And when and webrender hit the stable release (v60-61 maybe) there will be another noticeable improvement. Point is even more performance improvements are in the future.

    Not long ago I was on 52 ESR and the performance difference is HUGE. There will be many complaining about the loss of Legacy addons, and it is a loss, but I had very little impact from the loss of Legacy addons that is worth me complaining about. A session manager to replace the one in Tab Mix Plus would be nice, other than that, not going to worry about it. Comparable appearance to what TMP offered was taken care of with css. Other than a more robust session manager I'm good.

    • Powe November 14, 2017 at 11:14 am #

      Everyone is talking about the speed but can you tell me more about it?

      Let's see for example, the difference between IE and Firefox was really large in the past. Firefox can open web pages really fast compared to IE. IE needed to download an image fully first, contrary to Firefox which showed image as soon as it loads. Modern browsers don't have this problem, all rendering speeds are identical.
      So by speed, did you mean the browser startup speed? Firefox was the slowest, but 5-10 seconds slower does not make any difference to me because you only need to open it once not multiple times.

      I've been asking people at the comments but no one can tell me what 'speed' they're talking about.
      I'm serious here.

      • Richard Allen November 14, 2017 at 3:54 pm #

        IE 11 and FF is not a good comparison. Most every browser I have installed had faster startup times than IE, and on graphics heavy sites IE couldn't keep up with my scrolling, the others could. I wasn't quite sure on the IE dev tools when reading the timings, I'm used to the FF and Chrome dev tools. Page load time seemed a little slow, just guessing, I rarely ever even open IE.

        For me it's about startup (browser opens, page renders, extensions are loaded And actually doing what they are supposed to do) And page load times. Some people including myself open a browser numerous times a day, some people don't. If I'm not using the browser I close it. My reason for doing that is so 1st party cookies and offline website data, which includes indexedDB folders for some websites, can all be cleared when the browser closes, I do block 3rd party cookies but not 1st party.

        I have numerous browsers installed and in all of them I open one tab to the Startpage search engine which has half a dozen different elements being hidden with uBO to clean up the page, and it's not uncommon, with most browsers, to see those elements take a few 100's of a second to go away. Another extension I use is No-Script Suite Lite, which by default has javascript off and sites have to be put into a whitelist, with most browsers you can see the icon flipping from js not enabled to enabled while the page is being loaded, during browser startup. Point is, a browser starting up and rendering the page is not the whole story, unless you don't use any extensions.

        When I was using FF 52 ESR I'm thinking the startup time was in the 4-5 second range, FF v57 is for me about 2 seconds. Page load times in all browsers are fine and it's hard to see any difference between browsers without opening the dev tools but then some websites like bleacherreport, flickr and feedly do accentuate the differences. FFv57 on my hardware with my bandwidth is right there with Chrome, FF ESR was always one of the slower browsers but like I said it's not always obvious but with the dev tools open it very much is. It's hard to quantify the differences without actual hands on. FFv57 feels faster to respond to user input and smoother. No one that has used 52 ESR and then v57 can honestly say they don't see an obvious difference. I can perceive a difference just from v56 to v57.

        tl;dr - just try it and decide for yourself ;)

    • Powe November 14, 2017 at 8:42 pm #

      What I meant by IE and Firefox was the comparison between IE 5 or 6 with Firefox 3, you can see the difference clearly.

      Reading your reply I can assume because Firefox has Noscript so it's faster? Of course it will load faster because you don't load the scripts.. I don't use Noscript so I don't see any difference.
      As I said before, 3 secs faster startup time is not a strong reason to label a browser 'fast' to me.

      I've tested many browsers, people said Chrome is fast or fastest but I don't see what's 'fast' other than the startup time. That's why I still use Firefox because I don't see any difference, I assume Firefox 57 would be the same thing.

        The tab that all my browsers open with have javascript enabled. No-Script Lite is all or nothing for js and the vast majority of websites I visit have js enabled. I use No-Script Suite Lite mostly for the new websites I wander into so that js will be off by default in that case. In my comparison, all browsers were using js on the websites I visited. IE11 is also using ABP for IE and the EasyPrivacy Tracking Protection List and I use a hosts file but in reality very little if anything gets redirected by it.

        I constantly open and close my browser so the difference between 2 and 5 seconds is noticeable and annoying, for me. If you open your browser once a day then it doesn't matter, I guess. When 6 browsers open in 2 seconds and one or two others take twice as long the slower ones won't be opened often on my desktop. ;)

      I wonder if it's because of those forthcoming changes that XUL extensions need to go. I understand Appster's argument that the presence of XUL add-ons can co-exist with Servo (as demonstrated in v56), But still, v57 is EVEN FASTER, so what gives?

      But more importantly, perhaps the presence of older code will hinder the adoption of future performance improvements. And maybe more older code is on the chopping block (pertaining to functionality that has already been cut)

      The best tests would be for those who have enabled legacy add-ons in Nightly Quantum releases. Have any of those users notice performance decreases?

      • Richard Allen November 17, 2017 at 8:53 am #

        "I wonder if it's because of those forthcoming changes that XUL extensions need to go." I believe that it is part of the reason. And the argument that the presence of XUL add-ons can co-exist with Servo and using FFv56 as an example to maybe justify why it should stay that way is not telling the whole picture in my opinion. Servo/stylo in v56 is an early implementation and it's not even enabled (layout.css.servo.enabled). It wasn't enabled in Nightly v56 either. With servo enabled in v56 I have not seen any improvement in startup or rendering. I like to use feedly, flickr/explore, bleacherreport and a couple others for testing. Scrolling those pages with a mouse And using auto-scroll will show me a lot about how a browser is doing and bandwidth is not an issue on my end. The difference I'm seeing between v56 and v57 with rendering performance is very noticeable.

        Within a month of Nightly updating to v57, all of my legacy addons either quit working or had some serious bugs even though they were multi-process capable. That was when servo really started to be implemented. As far as Legacy addons working in Nightly v59, I'm not aware of even one that is still working.

        Because I wanted to show it can be done And because I have 'some' profiles saved going back to FF v31 ESR, I currently have FFv52.5 ESR, FFv56.0.2, FFv57, Nightlyv59 and Waterfox v55.2 installed. Not for long but it works well for testing. There are differences in startup time and rendering performance between all of those browsers. Using FFv57 as a baseline these are my startup results:

        FF v56.02 takes 30% longer than v57 to startup, render the page and load extensions.
        Waterfox v55.2 takes 65% longer than v57...
        FF v52.5 ESR takes 85% longer than v57...
        Differences in rendering are not as dramatic but still very noticeable.
        Right now, Nightly is slower to startup than v57 but still faster than the others, looks like they're messing with how extensions are being loaded during startup, just guessing.
        Above was done on Win7 Pro x64, (4 core) core i5 @ 3.2-3.4GHz and a fairly fast SSD.

    Firefox the most customizable and flexible browser on the market, died at version 57 from a serious case of a virulent butt sniffing.
    Developers tried resuscitating it by doing several bypasses to the engine and underlying technologies, but after many hours of hard work they were unable to bring it back to a former glory of yesteryear.

    Firefox made a small recovery, but due to what we can only guess were complications, has become unrecognisable after such a lengthy procedures by the attending developers.
    Firefox suffered massive memory loss in the customizability part of the brain, for one, it no longer remembers it was the most customizable browser on the market and doesn't even remember it use to support /* AGENT_SHEET */.

    Once a market leader in customizability, the leader of the pack, the alpha dog, is now just another mutt; just another butt sniffer.

    Many had hoped that Firefox would make a full recovery in time, but it is starting to look like it will never regain the glory of days gone by. You will be sorely missed.

        Firefox is a lame Chrome imitation, bowing down to leftists retarded demands and their own perverted form of "diversity" - Which strips conservative users from their right to customize the browser as Mozilla does embrace both... corporate identity and Flakes opinion that all what disturbs them is attacking their safe space.

        Thats what Mozilla is today. A bunch of radical leftists who sacrifice everything which smells conservative! And guess what, this is called facism and racism!

        I don‘t remember Mozilla contributing too much to Vivaldi, haha. If you mean Waterfox, then I can only tell you this:

        It is a rebuild, so what you are saying does not come totally unexpected. In fact, it is a rebuild removing all the crap from Firefox, and I prefer using Firefox without crap to Firefox with crap. You should learn to differentiate between browsing-related code and spyware code before posting such a comment.

    • Firefox_v0.8 November 14, 2017 at 9:48 pm #

      This sums up wonderfully FF once endeavor to be a USER's browser.

    It's finally here. It's going to be interesting to see whether Mozilla survives this milestone based on performance improvements, or if it goes down due to transforming Firefox into something else.

    It's great to see solutions like the CSS customizations, it does feel though a bit like the Windows 10 situation: users have to keep fighting against their own software with 3rd-party solutions/workarounds, struggling to make it work the way the want to. I am intrigued though - hopefully we'll see more useful WebExtensions in the future, before Mozilla runs out of time - or users...

  30. Doug November 14, 2017 at 12:48 pm #

    You mentioned the new ">>" menu designed for items that you don't want placed on the toolbar. That new ">>" menu is called the overflow menu. To implement the overflow menu right click on an item in the main toolbar and choose "Pin to overflow menu". From that point on the new ">>" overflow menu will be visible. I love it!

    • rip.firefox November 14, 2017 at 3:49 pm #

      The overflow menu has always been there, just now its more prominent due to the increased size of the graphics >>.

    can 56.0.2 and 57 be used side by side ?

    • Appster November 14, 2017 at 1:25 pm #

      If each one uses a different profile, yes.

    • Martin Brinkmann November 14, 2017 at 1:27 pm #

      You cannot install both, but you can run one as a portable copy. Make sure you use different profiles for them though.

      • Appster November 14, 2017 at 1:30 pm #

        Alternatively he may also use Waterfox instead of Firefox 56.0.2 - would be what he wants, I guess.

    • Richard Allen November 14, 2017 at 3:14 pm #

      YES, you can run both!!!!!!!!!!!!!!

      And it's not that hard to setup. Last night I did a clean install of v57 on top of v56. As I usually do I saved a copy of my v56 profile, just in case. So, a few minutes ago I had v57 and Nightly installed. Before I reinstalled v56 I added -p to the target of my Mozilla Firefox shortcut, right-click properties. Then, I clicked on the shortcut which will open the profile manager and created a new profile with the name Test. I then installed FFv56.0.2 into "C:\Program Files\Mozilla Firefox Test" using a "Custom" install, not the "Standard". You can not install v56 into the Mozilla Firefox application folder. After install, from inside the v56 application folder, I right-clicked on "firefox.exe" Send to desktop (create shortcut). Renamed the shortcut, added " -p Test -no-remote" to the Target. Right-clicked on my v57 shortcut and removed -p from the shortcut. And I currently now have a ridiculous amount of FF versions to pick from. LoL

    • Richard Allen November 14, 2017 at 4:40 pm #

      Couple thoughts, if you actually do it. Go ahead and let the installer add it to the start menu and also add a shortcut to the desktop, if you think you might keep it. Do NOT let it start when closing the installer, you want to make sure that you add -p Name -no-remote to the shortcut target first. Save your profile before doing anything. If there is any chance that you will open it from the start menu be sure to add the no remote there as well or the two profiles will get contaminated. Good Luck!

  32. Dianthus November 14, 2017 at 1:33 pm #

    What is all that fuss about? FF 48.0.1 on Xp with add-ons is still great and fast enough. Why you need to load a page in 1 second if 2-3seconds are good enough? I do not understand all this evolution BS. Everyone want new stuff fast but it's all buggy in the beginning. W10 is now beginning and I'm glad I do not start it when it came out with all the bugs and so on and this is the same with FF, iPhone X,....

    Have here also W8.1 and I will check it out soon but Xp with FF 48.0.1 with the necessary security hacks (browser + OS) works fine and I surf and shop all over the world. We need to stop in my mind with this quantity evolution. Make something quality durable and that last for years and make that it works for everyone but yeah that's the BS of free market and everyone that likes it. It makes garbage. Why not give one the browser, one the pc, one with that program and so one company or so but no everyone think they can make all of it and it's more garbage than quality. Why we need 10 browsers, 10 different OS, + 30 cars and so on? It's totally insane and with this system we never get really a break for all this because it makes more problems than it is worth and I can tell you that his is not going to last for very long....

    • Appster November 14, 2017 at 1:45 pm #

      Why don't you use Firefox 52 ESR if you are still on XP, though? That version shouldn't differ from FF48 too much.

      • Dianthus November 15, 2017 at 12:06 pm #

        Yes Appster I have that also but I have used every browser out there and the top for me is Avant Browser with the crystal skin and with FF engine and that I cannot update to the 52ESR. No other browser has the options of Avant but I do not want to make a fuss about it because I do not want Avant to become the mainstream top. Not good... :)

    Linux + WebExtensions is a major irritation right now:

    -WebExtensions for mouse gestures do not have proper behaviour in Linux (context menu is appearing when a right-click gesture is made). Some kind souls have posted a script that may unofficially patch the problem, but I have yet to try it and cannot vouch for its functionality.
    -WebExtensions that disable the ctrl-q shortcut do not work in Linux. I can get around this by disabling ctrl-q globally (system-wide), but this is obviously an extreme measure that I'd rather avoid.

    By the way: Is the "pure" (not hybrid) NoScript webextension ready yet? I can't seem to find it but I thought it would be out by now. Update: Found my own answer. Apparently it's going to be released TODAY!

      The best I could come up with is some css that goes in the userChrome.css file, which is inside a 'chrome' folder, which is inside the profile folder. The chrome folder does not exist by default.

      @namespace url(""); /* only needed once */

      #appMenu-library-recentHighlights, .subview-subheader { display: none !important; }

    • Richard Allen November 14, 2017 at 7:38 pm #

      I was able to make the css better by removing the separator. Duh! ;)

    Good bye Firefox, welcome pathetic Chrome emulation - guess all the customization hating web 2.0 crowd and all the Mockingjays from Panem's dirt who don't want to think and only consume must be happy now.

    Pale Moon and Otter-Browser luckily are for me good enough replacement ones.

    Here is my personal big middle finger Mozilla!

    And yes, Firefox was a power-user browser as long as Mozilla had in mind to develop for conservative users first instead for all the minimalist and simplicity craving leftists, flakes and SJW crowd who are hating feature diversity more than everything else as it offended their pride to face features and options they have been unable to understand :D

    • Sadaji November 14, 2017 at 8:09 pm #

      Not to forget...

      Firefox 57 - Chrome emulation with a different engine and square tabs... And a slap in the face for the guys who want to change the bar layout and love additional optional elements like a real status-bar.

      This is very much a "Do not touch our UI - it is a recognizable trademark" slap for all those people. What for a sincere vision... what for a step forward of Mozilla's old mentality to give users as much power as they wanted :D

      If a brand becomes more valuable than the users right to change things - And before the opposite was the case... well, there is one name for it which fits perfectly... Google Chrome! Mozilla's new beloved role model.

      A clear case of Anti feature/functionality fascism. Congrats Mozilla and welcome to the extremists elite club :)

      • Jody Thornton November 17, 2017 at 3:20 am #

        Oh my gawd! Fascism now? Aren't we getting a bit extreme?

        First off as for Mozilla wanting to boast a trademark experience, hey it's their browser, not ours, so why can't they do as they wish with it?

        Second, it's not your "right" to change things. The product is Mozilla's - not yours.

      • Sadaji November 17, 2017 at 1:46 pm #

        First, It is the right of the user to change things. If Mozilla does not want that, Open Source would be the wrong license to spread their product.

        And no, caling it the way it is - fascism - is not extreme. Mozilla is a hardcore leftist and anti options and choice hating for profit only construct. They have been different many many years earlier before they decided that all their future inspiration has to come from Google Chrome and that Google is the company in which they are in direct competition.

        Also, Google is a leftist company which gathers all the rabid SJW morons Mozilla wants to have these days too. Both companies hate both conservative users and oldskool features. Mozilla has been different as written many years earlier, but sadly none of that once proud and unique company exists anymore. The company which valued honest diversity is gone. It is dead.

        What is left is a disgusting racist fascist construct which tries to gather users of the same opinion.

        That is.. fascism in it's purest form. And for that, that assholes from Mozilla should go to hell!

    • Clairvaux November 15, 2017 at 2:49 pm #

      I have been following with some fascination this meme of Mozilla is ruining Firefox because they are a bunch of Leftists, while having many add-ons would be an inherently Conservative thing.

      While Mozilla is indeed a bunch of Leftists, and customisability might indeed be construed as Right-wing (as in free markets, private initiative, freedom of the individual), I would like to point, just for the sake of the argument, that security, privacy and resistance from snooping, which are some of the reasons for the switch to Web Extensions, might well be presented as Conservative values, although Leftists do cultivate them as well.

      I suppose much depends on who your adversary is. Finally, if you have guns (or shields), you can protect yourself against whomever you will -- and that, I would argue, is a reason not to overdo it with the Leftist Mozilla meme.

      • Sayan November 15, 2017 at 5:08 pm #

        This is hardly a Meme. Everywhere that rabid people lay their hands on is going to suffer. Uniqueness is going to vanquish and it is replaced with more of the same (conformity) not to anger possible fellow leftists or snowflakes or SJW in general.

        That is the reason why real diversity is going to die. And what that guys sell us in their words as diversity is just stuff stripped down to make sure everyone has their safe space.

        No, this is no Meme. This is the reality.

        This is a dirty sell-out of real and unique conservative features, visions and ideas. All to make sure that liberalism/leftwing ideologies and visions is the only thing to be found.

    Tested 57.0 on two "slow" computers, Acer D270 and Asus EeeBox EB1501U. Both are running Windows 7 32-Bit with all the Windows Updates including November 2017 patch Tuesday. Both are equipped with SSD drives and have 4GB of RAM. Neither computer have any kind of AV installed to slow things down. The very scientific test consisted of first starting YouTube on Google Chrome 62.0.3202.94 and playing "Taylor Swift - Shake it off" on 720p and then 1080p, followed by doing the exact same thing on Firefox 57.0. Also both browsers have uBlock Origin installed. The results were very clear: Firefox 57.0 was considerably slower in opening YouTube, also it took 8 seconds for the video to even appear after typing in the search box, and playing the video after changing resolution was also much slower than Google Chrome. Now Google Chrome is not doing these things lightning fast either, remember these are low end machines, but for basic things like YouTube, Facebook and so on, no other browser I have tested on these things come even close to the performance of Google Chrome. Believe me, I have tried 20 different browsers, and my hopes were skyhigh for Firefox 57.0. I guess the browsing speed I have on these things is as good as it's ever going to get. On better hardware you probably won't notice that much of a difference between Chrome and Firefox, but now you know that it's THERE..deep deeeeep down it's there =)

    • Richard Allen November 15, 2017 at 12:55 pm #

      Tested my Toshiba Satellite A505-S6986, Win7 x64 SP1, Intel Core2Duo @ 2.2GHz, 4GB DDR3 @ 800MHz, NVIDIA GT 230M, ADATA SP550 SSD forced to use SATA II. Manufactured late 2009, purchased early 2010. SSD and 2nd replacement battery both purchased last summer, everything else stock. I cloned the drive last year, probably should have done a clean install, plan on doing one. Using the newest versions of Chrome and FF.

      I hadn't tested my laptop in 2-3 months, I mostly use a desktop, and wasn't expecting much better results than what you saw. I've been using FF since v3 and I've had chromium browsers installed and to a smaller degree have used them for about 5 years. Used to be when watching 1080p 60fps video on YouTube, Chrome was the best choice. Browsers using uBO, Tampermonkey, Stylus, Magic Actions for YouTube and No-Script Suite Lite. Anyway, these are my results, average of three runs for each test.

      Browser startup: Chrome 6.3 and FF 6.1 seconds.
      Open YouTube bookmark: Chrome 3.5 and FF 3 seconds.
      Open and play "Taylor Swift - Shake it off" at 1080p from search results: Chrome just under 2 seconds and FF just over 2 seconds
      Open and start playing "JUMANJI 2 Official Trailer 2" at 1080p 60fps from search results: Chrome 3.5 and FF 3 seconds.
      JUMANJI 2 at 1080p 60fps dropped frames in 30 seconds of playback: Chrome 117 average and FF 68 average
      Six websites open (startpage, youtube,, bbc, bleacherreport and wired): Chrome 891MB and FF 828MB.

      Completely different results from a couple months ago where Chrome did much better but with a big price paid in resource usage. I did a quick and dirty upgrade to FFv57 and I'm surprised it worked out as well as it did. I had planned on doing a clean install which is what i did on my desktop, reusing some files from my v56 profile folder. As it turns out, Both Chrome and Firefox did very well on my almost eight year old laptop.

      • ChromeZilla November 15, 2017 at 2:56 pm #

        Surprised a bit by your findings, then again your processor is a BEAST compared to the abysmal Atoms that run my two monster rigs. I also should have mentioned that I tested with both browsers caches cleaned, no bookmarks, no pre-loading, both started empty and cold in incognito/private-mode. Good to see people testing/reporting on old computers, I feel that's what most people use anyway. Some 5-10 year old laptop is probably more widely used globally than what the industry thinks..? I also think that "Taylor Swift - Shake it off" should from now on be the industry standard in testing browser performance =)

    • Richard Allen November 16, 2017 at 5:40 am #

      MY processor is a BEAST?!? You're scaring me! I'm not quite sure if I should be proud or sad! LoL

      I started with cookies and cache cleared but... three runs. I don't use prefetch/prerender in any browser but I do use DNS preresolve which can also be configured in chromium browsers. In chromium browsers I use a bunch of flags and command line switches. Doing a clean install of FFv57 on my desktop I felt like I was changing 1000 about:config entries which is payback for not setting up a user.js file. I even go so far as to reduce the disk cache max entry size to 8192. All browsers limited to 100MB cache but chromium browsers look at that (command line switch) as a suggestion (cache spread around too many folders) and I usually see up to 150-200MB in them, at times. None of my installed browsers are at default settings. Actually, not even close. ;)

  43. Don November 15, 2017 at 12:50 am #

    Huge speed increase between FF55 with legacy addons, and FF57 with no legacy addons - both startup and page load. I'm liking it.

    I spent some time getting used to the new menu, and customizing the toolbar and overflow, and checking out the Options.

    The update removed the Bookmarks button and added a Library button. I use Bookmarks all the time and rarely use the other parts of the Library. Luckily, I was able to add the Bookmarks button and remove the Library button with Customize.

    I didn't like the Pocket button so prominent in the address bar. I wanted to just hide the button since it's in the Page Actions "..." menu. But the only thing I could find is to disable Pocket, so I did. I had always left it enabled because I might one day want it. Easy enough to re-enable.

    • Appster November 15, 2017 at 12:57 am #

      But you know that legacy add-on deprecation and Quantum are not even related, right? You could enable parts of Quantum in FF56 already, likewise there is an option to run legacy add-ons (with no guarantees of course) in Firefox 57. So...

      Does the Bookmark button open the bookmarks side panel with a single click ? I needed a ton of different add-ons up to now to achieve that very simple thing...

      • Don November 15, 2017 at 3:08 pm #

        No. But there is another toolbar button to open the Sidebars, and it remembers the last sidebar you had open: Bookmarks, History, or Sync Tabs. If you last had the Bookmark sidebar open, the button will open the Bookmarks sidebar. Search for the button with Customize.

      • Clairvaux November 15, 2017 at 3:18 pm #

        Ha ! Thanks... Why does Mozilla hate bookmarks ? Why do they hate people who use and like bookmarks ? Can't we all get along ? Let this sink in for a minute : the super-duper Firefox, the last and best extraordinarily enhanced version of the power-user browser Firefox, still does not offer a way to show all bookmarks with a single click.

      • Don November 15, 2017 at 5:16 pm #

        You might be interested in the "Popup Bookmarks" extension. I just started using it. I don’t like the font; but it’s very handy.

        Mozilla doesn't hate bookmarks. It's the *organization* of bookmarks that's given the cold shoulder. And their right to be that way for the most part - most people do not organize their bookmarks, despite their initial aspiration.

        The Address Bar handles most bookmark work for most people; click the star button to add, edit, and remove a bookmark; type in the address bar to find a bookmark. And the Bookmarks Toolbar is great for those who like to click rather than type for frequently visited sites.

        The Library still feels disconnected from the browser. I’ve been expecting it to move into a browser tab ever since about:downloads appeared. The library needs an interface consistent with the rest of the browser. But it’s only used for occasional maintenance of bookmarks, so I understand and don’t mind that work on it is on the back burner.

        "It's the *organization* of bookmarks that's given the cold shoulder."

        Exactly. And that is dumbing down. To me, bookmarks are just files, and I want them organised the way I organise them with Windows Explorer, Directory Opus or another of the multiple tools available to that effect.

        While I perfectly understand that many people may be content with searching inside their bookmarks, or, maybe more often, on the Web, it remains you need to organise bookmarks if you're serious with them. I have 15 000 bookmarks, so I need my own organisation. As much as I appreciate FF search function in its intelligent address bar, and it's indeed very handy, I need to have my own filing system on top of that.

        Also, there's no way I could be sure to find one of those Web pages if I only relied on Google, or other search engines, to that effect.

        Of course, online search is where part of the money is to be made. When I look into my bookmark folder hierarchy, that does not bring a cent to Mozilla, Google or others.

        When you think of it, it's amazing how this simple tool has been taken away from us. And it's not only Firefox. The first version of present-generation Opera had completely done away with storing and filing bookmarks locally. Which they had to correct, following users' outrage, but only very partially.

        This is a trend, and goes way beyond bookmarks. We're being morphed into a generation of lazy zombies, content with clicking away on the Web, or the so-called cloud, and surrendering control to whatever corporate entities, for-profit or non-profit, may be pulling our strings on the other side.

        This is not good for the user, whether he's a power geek or the proverbial grandfather barely chugging along. (Some of those grandfathers have actually invented computing and the Internet, so maybe this metaphor is stale by now.)

        Thanks for Popup Bookmarks, I'll give it a try, anything may come handy.

      Back when Nighlty updated to v57 I was looking for a replacement for the "Bookmarks menu" addon and have been using "Popup Bookmarks" since then. I thought the font looked fine in Nightly then when I upgraded v56 to v57 by doing a clean install I then realized the default font is Times New Roman which I think looks pretty bad in the addon. I have for years set the browser font to Tahoma and the minimum font size to 12. Might be worth a try, it does change the addon font.

    Just got the dreaded call from Dad. He got auto-updated to 57. He is no longer able to go to any site with a log in, hanging when trying to log in to facebook, gmail, etc. Finally had to move him on to Chrome so that he can use the web. Sad.

    The best part of FF57 is the broken download manager, that constantly thinks files failed to save, but actually successfully saved them, that DELETES the files FF thinks didn't save (but did), if you clear download history or exit Firefox.

    Best feature yet.

    Saw today that Mozilla has dropped Yahoo and made a new deal with Google which again makes Google search the default search engine in Firefox in the United States, Canada, Hong Kong, and Taiwan. I can't say I'm entirely happy with Google controlling Firefox's purse strings again...

    Mozilla finished their leftist craving journey finally and sell out advanced folks for narrrow-minded leftist needs who already get a meltdown when they realize there is something onboard which possibly could offend and overpowering someone.

    Very cool Mozilla - every Communist gov would have been proud.

    Love this latest release. I've been lucky, as all the addons I needed were available as webextensions. But for some time I'd been getting disillusioned with Firefox over speed issues - it really dragged its heels even on a decent system. I was simply staggered with the speed of this release.

  49. passerby November 15, 2017 at 4:29 pm #

    What justification is there for calling it "Quantum"? Do they take their advice from quantum healers?
    Just the use of this single word makes the entire project suspect and says something about the mentality of its developers.

  50. TarekJor November 15, 2017 at 7:07 pm #

    Thanks for good article, Martin

    I am optimistic with Firefox Quantum (even after XUL purge), at least "safe" for now, with the "commitment" of people behind WaterFox and "Mozilla parallel forks" (possible but non-secure future), and "AMO" archiving

    For now, I am on Firefox 52 ESR (personal config + addons) and Firefox Quantum both installed...

    The thing is I am now, searching about how doing good migration from some legacy addons, if possible, and the importance of preservation "good feaures" and utilities as addons which will be deprecated, purged (in name of "modernization"), addons as work, and developers behind deserves memory, respect and archiving.

    I salute you, respected users and community :)

    Anyone find an alternative to Googlebar Lite? Way back it was Googlebar then I started using Googlebar Lite. It's now dead with v57. Really going to miss this one.

    Mozilla's support for radical morons and other issues (found on some random music page - edited for better understanding as the writer had clearly issues with the English language):

    They support Antifa, SJW and radical leftists which have the goal to replace culture and law of each land with a foreign culture and law - most prominent Sharia and radical Islam. All that offenders have in common that they despise the origin culture and it's way of life and the ruling laws

    They remove everything which makes Firefox different, special and unique in direct comparison to the competition and instead make it generic in look and function to make sure that the software only has functions that the most generic users would be able to understand and use - everything else would be removed - which includes removal of XUL, full themes and UI customization - to gain the support of radical SJW/leftists who can't accept anything else than their own "visions" and refuse the fact that people have different abilities and skills and therefor have to be treated in a different way, also not to forget the safe space argument. Who can not understand a thing could be possibly be offended, which is seen as inappropriate and shall be avoided by all means necessary.

    Mozilla's dislike for Conservatives, Christianity, traditional values, users with knowledge and previous community members who delivered add-ons and full themes for people with above-generic skills and for people with at least half of a brain

    Mozilla not fighting for Brendan Eich and their focus these days only on Chrome users and abandoning their origin user base consisting of geeks and experts.

    A really lost cause!

        That is far from being an conspiracy theory.

        This is what happens when a company who once honored both - not skilled users and geeks - is suddenly bonding with the most utter trash opinion available on this earth.

        Resulting the company too gets utter garbage. Mozilla guys are spineless and dishonest fanatics without the smallest sense of loyalty for all their oldskool users.

  53. Torro November 15, 2017 at 11:09 pm #

    Well i upgraded and had forgotten that 57 was not compatible with legacy add-ons. And while FF57 is extremely fast, compared to 56, I reverted back to 56 until No-Script is ready for 57+.

    Funny thing too, when i installed 56 over 57, i still ses some speed improvements leftover from 57. Granted not as quickl as full 57 but faster than what 56 was prior. Either way, my add-ons are working once again.

    I see some reactive "noise" and disorientated people here (leftist mentions and similar shit-stuff) ctrl+F to identify) 12 matchs

    People who want, serious debate (beyond desorientated trolls), with some moderation around Firefox 56 ESR (Waterfox) and Firefox Quantum (maybe in future WaterFox Quantum go r/Waterfox or r/Firefox respectively on Reddit) if you thing that projects have a POINT, then collaborate and involve...

    The Point is for now, saving legacy addons, and XUL XPCOM addons extended development (in future) via WebExtensions or XUL-fork

    MozillaZine is serious too, too (but I prefer Reddit)

    I am now using Firefox 52 ESR (waiting for Waterfox 56 ESR (with legacy addons support) I don't accept Firefox57 purge of legacy-addons (WebExtensions are not mature yet) (so I am using that)

    BTW: For constructive-criticism go to collaborate with Waterfox or PaleMoon team and community (Facta non Verba approach) (Facts not Words)

    We together would be able to create alternatives to the bad decisions Mozilla has made (opinion shared by vast of many, but all is us need a go-go-go and get involved directly (beyond plain complains on forums, blogs or social media...

    Generally I DO NOT LIKE CHANGES. I would still use XP, since I could work with it on most applications even without the monitor... therefore old fashion guy but spending 25 hrs a day on the PC professionally. The new Mozilla FF (57) is digestible, more or less. It is faster though! - What I strongly dislike is the size of the bookmarks bar. It used to hold all my bookmarks in one line. Now it is extended in 1.5 - to 1.8 lines. If I wanted to search for bookmarks I would find another slow way for searching each of them. What is the use of the speed when I need to look for the bookmarks in two lines instead of one. And I have built them throughout the years exclusively to be in one line.

    For me Firefox 57 the new tab page is less flexible. I use to use a local HTML-fil to define my own web site for new tab, and I used New Tab Homepage add-on for make that happen. Now this add-on is out and I try New Tab Overrite but this does noe allow local file. Why not? Actually I might install web server to solve this but that's a too big operation only to solve new tab page problem. I am looking at a possible solution in about:config but I am not sure what to use. Any suggestions?

    Its about as bad as I expected:

    No status bar, can't get rid of stupid pocket and reader icons, most customisation options gone, writes to hard drive every 3 seconds even when inactive, still can't increase cache above 1024MB, using 500MB and 7 processes just to hold open 7 pages.

    Absolutely terrible. Literally as bad as chrome.

      yes but surely you knew all this prior to installation.There has been enough press in this regard for months.
      Constructive criticism is all well and good,but complaining and whining for the sake of it is becoming tiresome.
      I see it all over the place now.Complainers in full prior knowledge of all the changes yet install anyway.

  62. TarekJor November 16, 2017 at 8:43 pm #

    About the complain about the complain (iteration), yeah, but thanks to Freedom of Speech, we as civilizated humans are be able to "agree" or "disagree" without impositions... even if people is tedious (we must not to censor that), we can ignore and respect others or not?

    About constructivism, all the people who wants to "disagree"*(1) with Mozilla, purging XUL and legacy addons, after the complain, is encouraged to join emerging projects like WaterFox, PaleMoon team with Basilisk, etc or using Firefox 52 ESR (until 2018-Q2 with security patches), r/Firefox or r/WaterFox on Reddit, or PaleMoon community, to join people agree with that *(1)

    This is all about, Open Source, Freedom and Creativity, is that "tedious" maybe for someone... but that is about "collaboration" and contructive criticism.

    People has to complain, people (don't to informed, because it is "normal" not only is a "browser developer" or a programmer, now, hash some shock about "legacy addons" purged, so it is normal

    Unfortunately I'm very disappointed with the new look of Firefox. For me it looks ugly as hell. There's something extremely amateurish about the overall graphic design of the tabs and the folder icons in the bookmark bar. The whole thing looks like a non-professional skin from 15 years ago. The dimensions and the sizes of various elements are somehow off. I mean wth is going on with those hard square tabs? I'm using the browser in Windows 7 on a 27" screen.

    I don't really have an opinion about the speed at this point. It's probably slightly faster to use, but I did notice that a rather heavy Google Docs spreadsheet was still quite heavy in Quantum.

    I did use Quantum for a while until returning to a previous version a few weeks ago. I had forgotten the whole Quantum thing until an updater software automatically updated Firefox and it all came back to me. And now I guess I'm stuck with this. I do use Chrome a little but Firefox is my main browser and I've no plans to ditch it even if I'm not too happy about it currently. I seriously hope Mozilla's graphic design team takes a long look at the current design trends and makes the browser look modern. Plainly put designwise Quantum does not look balanced or polished.

  64. kode November 16, 2017 at 9:02 pm #

    I forgot to mention in my previous post that the main reason I ditched Quantum earlier was that it refused to download zip-files from Amazon AWS. A reputable freelancer site I use collects all the pics a client has into a zip-file and stores them at AWS, and then offers the download link to the stored file. It took me a second to realize Quantum was the reason the files weren't starting to download. And now I was reminded of that once again when it turns out the downloading is still not working.

    I've no idea who's to blame here? Am I too stupid to realize that I should be doing something that's always worked in previous versions of Firefox? I didn't find any setting in Quantum to solve the matter. Is Amazon to blame? Or my freelancer site?

    What a bloody mess. I guess I'll have to downgrade Firefox once again and disable the automatic updating. FU Mozilla. What the hell is the matter with you?

  65. Clairvaux November 16, 2017 at 10:16 pm #

    I have now 3 different versions of Firefox installed : pre-Web Extensions Release 56.02, pre-Web Extensions ESR 52.4.1, and post-add-o-calypse Quantum Release 57.0.

    Each has two profiles : one default, empty, which stands unused as a reference ; and the other, in use. ESR was loaded with my last pre-v.55 profile, and Quantum with my last 56.02 profile. That will allow me to experiment.

    I also applied different themes to the different versions, in order to make them stand out.

    First observation is you can't have one Profile Manager for each different install of Firefox (hopefully someone could prove me wrong). You may save each profile wherever you like, but that's of no practical use, because Firefox will create a single profiles.ini file for each Windows user account, in its default place of %AppData% \ Roaming \ Mozilla \ Firefox.

    Which means, each time you fire up the Profile Manager, you're offered with an opportunity for a mistake, by choosing another Firefox install's profile. (Which you could use, but shouldn't.) Unless you elect to always launch each version with the same profile, automatically, but it then defeats the whole point of Profile Manager. Again, please tell me if there's a different way.

    Another thing is the new add-on repository is alluring, but quite problematic. For instance, barring any mistake on my part, if you select a category of themes, and you have 500 pages of them, you can't jump to, say, page 498. You need to click Next 497 times.

    Also, Quantum breaks my Cinta Notes workflow, which is a major crime to me. The whole point of Cinta Notes is, I can select text from a web page, hit Ctrl + F12, and I have created a Cinta Note with the text, the Web page title as a title, and the URL in the URL field. Now this is broken for some mysterious reason, and opens instead a Google Translate page. Which is nice to have, but not if it breaks other things.

    • Anonymous November 17, 2017 at 9:45 am #

      Firefox 57 Portable and CintaNotes Portable "installed" here. Ctrl + F12 works perfectly.

  66. Clairvaux November 16, 2017 at 11:48 pm #

    Let's have a look at Quantum's glorious bookmark stupidity (which has not much changed since the previous generation, but we've lost the add-ons that helped to paper over the cracks).

    I'm installing Firefox. Now that's a browser, and I'm told that keeping bookmarks is a basic feature of a browser. There's no blasted command out of the box called Bookmarks on the screen : no icon, no menu item, nothing.

    There's something called Library, but Library is a nebulous concept which is not bookmarks. There's something called History, but, hey, that's also something else. And then there is Show Sidebars, which, again, does not scream bookmarks, although you might guess that's a step in the right direction.

    Now what happens if I try one of those three buttons, bookmark-wise ? The answer is, usually, nothing.

    I can click on History, but then I need to click on View History Sidebar, provided I guess in advance that once there, I will be able to click again on History, and switch to Bookmarks. That's FOUR clicks from the first level of user interaction, just to display the blasted bookmark tree.

    I can also click on Library, then on Bookmarks, then on Bookmarks (left arrow) again -- and I'm back to the previous menu : fail ! So we do this all over again : Library, Bookmarks, Bookmarking Tools, Bookmarking Tools (left arrow), and boom, once again : fail ! I'm back to the previous menu. Let's have another go : Library, Bookmarks, Bookmarking Tools, View Bookmarks Sidebar. At last we're there, and that's again FOUR FRIGGING CLICKS. Except if you have been taken for a ride by the stupid menu design, in which case you might have clicked TWELVE times just to open the bookmarks panel.

    And finally, I can click on Sidebars, and if I'm lucky, and the last time the panel was open it was bookmarks that were selected, I will have reached bookmarks with just one click. Otherwise, I need to guess that behind the History Panel, there is a Bookmark panel ; and that will take THREE clicks from screen one.

    Ah, but there's the "hamburger menu" on the right (because obviously, everybody eats hamburgers, and equates three horizontal lines stacked one upon another to a hamburger). I'm told that's the super-duper menu you go to when you don't know where to find something.

    So I click on it, a loooong menu drops down, and of course there's no mention of bookmarks, because, hey, who's ever heard of using bookmarks with a browser ? Maybe More is the answer ? Nope, there's only Text encoding and Work Offline behind it. Why you would put one More item in a menu to open a sub-menu with only TWO items is beyond me, but then I'm not an open-source developer.

    Maybe Library would do the trick ? No, because it opens exactly the same menu than the Library icon on the front screen, so this just adds one extra, useless step.

    Now I'm getting really really geeky, and I go into Hamburger / Customise. I'm told that customisation is only for hairy dudes who understand code, but let's be foolish for a while.

    I find there, dumped into a smelly cesspit of available... things ?, something called Bookmarks Menu. Why would Mozilla chose to hide it there is one of the big mysteries of the universe. Anyway, I stick the Bookmarks Menu on the toolbar, and then, I can reach the bookmarks panel with the incredible speed of TWO clicks.

    Provided, of course, I don't stumble upon the landmines setup in-between by your friendly Mozilla programmer, and choose, instead of View Bookmarks Sidebar, the confusingly similar Show All Bookmarks (of course, I want to see all bookmarks !), or the other Show All Bookmarks item which is on the bottom of the menu (does it do something different ? and if not, why have twice the same command ?), or Bookmarks Toolbar (what's a bookmarks toolbar ? and if I do feel an irresistible craving for one, why is the next step another command called View Bookmarks Toolbar ?), or (good heavens !) Other Bookmarks (other than what, pray, gentle lord ?).

    Amusingly enough, the Library icon on the home page does not open the Library (you've got to jump through a number of hoops to get there), and when you do reach the Library, you realise it has not changed an inch since... ever. And it has been in dire need of an overhaul for a very long time, because its organising capabilities are really very primitive.

    To the best of my recollection (and I'm certainly not going to try and check with a non-Quantum, no-extensions version), this is exactly the bookmark situation we have had with Firefox for years, maybe a decade, even.

    And I have not yet entertained you with the lack of organisational capabilites of Firefox's so-called bookmark "manager". I was just trying to get there.

    So that's why I proclaim that Mozilla are nothing but a repellent bunch of bookmark haters, and we're obviously in need of a law against bookmarkophobia.

    I think it's time to accept the hamburger menu now. It's a worldwide standard in GUIs now.

    • Clairvaux November 17, 2017 at 4:12 am #

      No. The number of people embracing stupid things is not an argument.

      One of the very good reasons this is bad design, is it's something you cannot name. Software objects need to have names, because software needs manuals, tutorials, how-to's, blogs, forums and the like. How do you name the _ menu ? Not the hamburger menu of course, because that's ridiculous, unrelated to the program, and actually the publishers themselves don't use that word very much, for all those reasons.

      So you're left with saying : the thing with lines over there, and there are three of them, and they are horizontal. Great ! How very helpful ! Or, you put up an icon, and you're back to savage country, before we even invented writing. And you can't even read aloud what you just "wrote".

      Another reason is : nobody knows what is in there. Which is natural, since it does not have a name. Is it a point of entry, the top of the hierarchy ? Is it a dump, a place where you put what does not fit elsewhere ? Nobody knows, and nobody says. So you just click away on it, because, hey, maybe there's something interesting there after all.

      That's not a piece of software : it's a bad video game.

      • Jody Thornton November 17, 2017 at 1:49 pm #

        As for the hamburger menu being bad design, for those who have used mostly phone and modern OS/apps, they have taken to the hamburger menu pretty well, which shows those who are resistant to it, just don't like it or don't want to adapt to it. Modern users find it intuitive. After all, as you say - if you don't know what to press, there's the hamburger menu.

        And who cares if you can't name it (actually the "hamburger menu" has become its name). Do most people know what the term "caption buttons" means? No but they know to click an "x" to shut a window or task.

        Enough with the analysis. You're just coming up with reasons to be biased against it.

      • Clairvaux November 17, 2017 at 2:53 pm #

        @ Jody Thornton

        A fine instance of "hateful" reasoning. Shall we say leftist ? "Mozilla-like" ? Or, more simply, dishonest and aggressive ?

        Since you won't stick to facts and arguments to support your opinion (which you are perfectly entitled to, like everybody else), you absolutely need to slander the opposition : they don't just disagree with you, they "resist". Because, as everybody knows, resisting is bad.

        "Modern users find the [menu-without-a-name] intuitive". Says who ? Broad generalisations based on absolutely no facts, just because you can't be bothered to explain your personal preferences. Explaining takes thinking. Thinking might enlighten others -- but it also might make you reconsider some of your opinions. Why is it you need the (imagined) support of others to like the hamburger menu ?

        Of course, modernism is a value. Everything that is newer is better. As we can all confirm by looking around us. Not being modern is one of the worst insults that can be hurled at people who disagree with you.

        People who "don't want to adapt" to the latest fad are dangerous individuals. We have the means to make you adapt. All resistance is futile.

        The leftist, Mozillist, "hater"-type or plain dishonest folks are of the irritable variety, too. They are important people. They have greater things to attend to : "Enough with the analysis". Since they themselves have little to contribute in terms of analysis, it's better for them that this phase be over pronto. So they take the bullying stance, and state : "Enough with the analysis".

        Then we have this little gem : "You're just coming up with reasons to be biased against it."

        You have to admire the talent of this category of people, which will remain as nameless as their favorite menu, to contradict themselves wildly in just a few words. Their opponents are supporting their opinion with reasons -- and that's why they call them biased, while biased means precisely airing opinions devoid of supporting facts. They pretend the opposition's reasons are not good enough -- but one second ago, they proclaimed that analysis was a boring thing, and that trying to shut up others with your own unsupported opinion was the way to go.

        That's too many words to say : I'm just happy to go with the flow, being a mindless consumer of everything the tech industry throws at me is my thing, and I resent anyone whose dissenting opinions might remind me of my fecklessness.

        Here comes the terrifying dictatorship of the lazy and dumb, which is so prevalent in the tech world nowadays. It's not enough that they are slaves to their trinkets ; they will deeply hate you if you're not a slave, too.

        Ewwwww Boy
        (to quote Fred Flintstone).

        Man, do you ever have too much time on your hands. When you take this Firefox/Hamburger Menus conversation and turn it into some leftist-agenda political crap, you have begun to WAYYYYYY overthink this. And turning this into politics is actually a bit dangerous, because then you make it sound like we have an agenda. I don't! I just like Firefox Quantum, and it's super-fast.

        No one (Including me) is forcing you to do anything. But the way you're going on, you're basically saying that anything that has become worldwide convention (take no smoking signs, international symbols, close buttons, and even hamburger menus) is part of some left-wing agenda against conservatives? Are you for real?

        To quote you:

Thinking might enlighten others -- but it also might make you reconsider some of your opinions. Why is it you need the (imagined) support of others to like the hamburger menu ?]

        Says anecdotal observations you twit. My lord, just look around. Look at all those people using smart phones with mobile interfaces, without complaint. You can just use your eyes. Not everything has to be researched to the hilt to backup a bloody claim. That's like asking me to prove the sky is blue. There's nothing wrong with gathering facts, but there's no need to go digging for facts here - only because the observations are easily apparent. If you can't see all of the everyday average people using a mobile interface intuitively, then you're stubborn or blind.

        Holy Jeez!

    Does anyone know of any web extensions or any other ways to gain the functionality of any of these add-ons:

    Calomel SSL Validation
    Cookie Controller
    Digger Reloaded
    Download Status Bar (easily show checksum)
    Enforce Encryption
    Revert Keyword Column (could this be done via CSS?)
    Toolbar Buttons

    Is there any way to have or make toolbar buttons to:

    “Undo close tab” (re-open the last closed tab)
    Toggle cookies on/off (a la Cookie Controller)
    Toggle the Bookmarks Toolbar on/off

    Finally, does anyone know specifically if it would be possible to add the “Encrypted connection enforced?” and “Start enforcing” button to the View Page Info, Security box–like the add-on Enforce Encryption does–via CSS?

    Thanks for any and all help!

      Restore normal version of firefox (56) and never update to new trash.
      Works fine for me. Hope Vivaldi gain new functions faster, so I can say goodbye to such incompitent developers.

    Who did the ugly black design and how can I get the old look back? Anyone knows?

    • Anonymous November 17, 2017 at 10:33 am #

      Firefox has never had a good "old look" black design, except with full themes which are no longer compatible.

    Ditched FF with it's all shiny routines almost a year ago. Currently i am on Cyberfox [it is ESR based on FF 52 code].

    After decline of CyberFox [it will be dead next year] will be forced to use Palemoon [it is in active development].

    Although we have Vivaldi, but it is based on Chrome code and i don't like it at all..

    So, future is not defined..

    May be Martin or someone can answer this, would be appreciated. On the 57 New Tab page, is there a way to open top sites in a new tab by default?

    About leftist comments. (to make some clearity, or throw light on some desorientation I saw)

    Left vs Right (it is moron discussion, honestly)
    Fascism and URSS are not the fame (but are similar), so Comunism on URSS is similar to Fascism... (but is not the same), and is not the same (no same causes, no same principles), even with common "factor" "Authoritarism".

    I don't agree with Communist and not with Fascism either (Violencia of unique Autorithy is bullshit)

    Anarchism & SocialLiberalism is my though (beyond the "desorientation)

    This Mozilla way, the XUL legacy addons purge, I felt as an agression (honestly) to my Freedom and Free Will on choice, and in OSS this is even more relevant.

    We could speak about Freedom vs Liberty (but is not the topic here)
    Software is very related to "Freedom" as a tool to... but please "serious debate" around it.

    Left (bad or good) vs Right (bad or good) => is moronic, Please read about "Nolan Diagram", and learn about "future and real Politics" beyond "Fronts" which don't explain anything.

    • Sadaji November 17, 2017 at 7:23 pm #

      Still does not change the issue that what Mozilla is all about today is indeed at least fascist/racist flavored.

      And what they sell us as "diversity" - is nothing else than a mono culture which supports only the one's who want everything being streamlined so that it fits the most dumbest moron like a perfect suite out of the box.

      And who is heavily discriminated for that? As you said already.. People like you! And all the other one's who want to have a more broader diversity concept feature wise, one which is not only limiting itself to the most idiotic people around!

      And what surprise... majority of those are from the leftist/liberal political spectrum! Those who deny Conservatives a fair possibility to speak in universities, those who constantly propagandize their special leftists religion darling and call harmless Christians rules on the other hand "Christianity Sharia law" and those who call everyone bigot who is not 101% on their side!

    Hello, can you help?

    I guess version 57.0 was automatically updated on my system.

    Speed dial is gone. Is there a way to retrieve it?

    Thanks for your help.

  76. Jake November 17, 2017 at 9:17 pm #

    Speed is great, can't deny or argue about that since life is finite. But it's visual appearance leaves /very/ much to be desired ... *painful wince*

  77. Tony November 17, 2017 at 10:23 pm #

    Version 57 is a disaster... no support for plugin developers, a lot of them would NEVER work on new version? So why would you accept this chromium clone? Pff.. goodbye mozilla team.

  78. Yoav November 17, 2017 at 10:28 pm #

    So, out of curiosity I took the new FF for a spin, using the portable version. On the upside: it looks great. What I mean is that all the sites look better in this version - everything is much sharper and well-defined compared to other browsers. I haven't noticed that it is much faster than my regular browser (waterfox), but then, for me, anything after the dial-up modem seems fast enough. Memory usage is pretty bad: about 1 GB for 8 tabs and four addons (ublock, treetabs, foxytab, and reader, working on 64-bit windows with 8 GB RAM). Waterfox running 25 tabs and 15 addons uses less.

    The downside is the lack of addons. For instance there are 13 addons listed for tabs, none of them coming close to providing previously available options. And then there is the impossibility of customizing the browser. Yes, it is possible to use css - but it is almost impossible to find fixes for all the things that have been taken away and anyway, who has the time for that?
    There is a new wiki for some basic things here:
    but that's almost nothing. For the rest - you can search through css sheets that other people have made to find what you need - and good luck with that. For instance - I want the X on every tab. How on earth do I get it back? I want a tab opened from a link to open in a new tab - and not replace my current one (who thought of that anyway?!) and I want to decide where this new tab opens - next to the current one or at the end of the tab list. I'm not going to bother to look up this stuff.

    So, bottom line: it looks great for a browser, but this is not the firefox that I knew and loved at all; at best, it will eventually be a slightly more customizable version of chrome - kind of like Vivaldi, which is less pretentious and more easily customized. Anyway, this was my two cents. You're welcome :)

    Reverting to 56. I can't live without simple javascript and image switch on the toolbar. All WebExtensions suck at that department. Colossal stupidity to not provide api for such a basic functionality.

    Looks like crap from the early days of computers. White, green, and red orange text on black screens went away with the advent of CGA monitors in the 1980s. I'm glad the light theme is still available.

  81. JP November 18, 2017 at 8:52 am #

    Hate the new design, went back to version 56. You can keep 57, NOT INTERESTED.
