Firefox 4 : Find out what is new

Mozilla will release the final version of the long awaited web browser Firefox 4 tomorrow. This ends an odyssey full of delays that began about nine months ago with the first beta release of Firefox 4. Nine months, that is the projected time that Mozilla will need for the next three major Firefox releases.

I have followed the development of the browser from pre-beta to the final release, and have to admit that it was not always a pleasant ride. It looked in the beginning as if the developers planned to make changes for the sake of changes, and not because they made sense or were demanded by the majority of the Firefox community.

Features like the new tab management module Panorama or the move to display mouse over link addresses in the address bar caused quite a stir among the community, and were disabled or changed in the end.

So what are the dominant new features that have been added to Firefox 4?

One can say that the new version improves the browser's core considerably. The developers have made the Mozilla Firefox web browser faster, so that it does not take the rear ranks anymore in web browser benchmarks. The JavaScript performance alone has been improved by a factor of three (or more depending on the benchmark) when compared to the current stable Firefox 3 branch.

The version offers now comparable speeds to other fast browsers such as Internet Explorer 9, Opera or Google Chrome.

Firefox 4 comes with improved web standards support, including better CSS3, HTML5 and web graphics compatibility. Other notable features include hardware acceleration support, support for the HTML5 video WebM format, out of process plugins for Macs (Linux and Windows have it built-in since Firefox 3.6), privacy enhancements and multitouch support under Windows 7.

Interested users can load an overview, that compares the changes with previous Firefox browsers, on the Mozilla website.

As mentioned earlier, the Firefox interface has seen quite some changes. The dominating additions are the new Firefox button at the top of the browser that leads to most options of the menu bar. The menu bar has been removed as a result, and tabs have been moved above the Firefox address bar. Lastly, the status bar has been replaced and is now hidden by default.

Check out Firefox 4, How To Undo The Changes for instructions on how to revert the changes (get the old menubar back, move tabs below address bar, display status bar).

The add-on manager has been changed as well, it displays now in a tab instead of a standalone window. It is likely that some add-ons that have been working fine under Firefox 3 will not work under Firefox 4. You can try and force compatibility the following way:

Enter about:config in the Firefox address bar and hit the return key. Accept the warning message if this is your first time, and right-click on a blank spot afterwards. Select New > Boolean and enter the value extensions.checkCompatibility.4.0. Double-click the entry afterwards after clicking OK and change the value to false.

Firefox 4 Download

The final version has been pushed to the Mozilla ftp server where it is available for all supported operating systems and languages. It usually takes between 24 and 48 hours until the release is publicly announced on the Mozilla website. We do know however that Mozilla will announce the final release tomorrow, which is the time when downloads will become available on the web page.

The only option for now is to download the release from one of the official mirror sites (for instance this one) or from one of the big software portals. Softpedia for instance lists the download already on their download portal.


The Firefox developers have already announced plans to ship a first patch shortly after the final release has been published on the website, as it is likely that the increase in users will reveal bugs that have not been discovered before. Plans overall are to release three new major releases in this year, which would mean a Firefox 7 release at the end of the year. Plans are plans on the other hand, and we have seen how delays can break them.

Firefox 4 Release Candidate Released (2011/03/09)

Many blogs have reported in the last days that the first Firefox 4 Release Candidate has been uploaded to the Mozilla ftp server. A release candidate build, and not the final release candidate, was spotted by one blog and almost every tech blog in my RSS reader reported about it. Let me be the first to tell you that the real Firefox 4 Release Candidate has been published just a few minutes ago.

The release is currently available on the release server, and various mirrors throughout the world. Most mirror servers and the original Mozilla server block the download of the new release. One that does not is the server of the Umea University in Sweden. Just scroll down to Europe and click on that server to download the release candidate early.

firefox 4

The release notes page has not been uploaded yet. Users who have updated to or installed Firefox 4 will get a page not found error. It is likely that Mozilla will enable automatic updates and the release notes page in the next 24 hours.

Users of the beta of Firefox 4 may need to make a change to the Firefox configuration, if they have used it to override add-on compatibility. They need to write about:config in the address bar and hit the enter key on the keyboard.

The new setting to override add-on compatibility in Firefox 4 can be added with a right-click and the selection of New > Boolean from the context menu. The new value's name is extensions.checkCompatibility.4.0 and it needs to be set to false.

Firefox 4 will not check an add-ons compatibility with the parameter set to false.

I will update the article when the downloads and the release notes page go life. (via)

Update: Mozilla has published the What's New Page and the release notes. The release notes state the Firefox 4 contains "general stability, performance, and compatibility improvements". The list of fixed issues contains several hundred entries and is accessible here. The release notes page lists the downloads for all Firefox 4 RC versions.

Firefox 4 to be released on March, 22nd (2011/03/17)

Well we've only just had Internet Explorer 9 out of the door on Monday but coming up straight behind it will be Mozilla's new Firefox 4 just next week.

More's the point, the company is so confident that people will want to grab the browser as early as possible they've given a release time of 7am PST.

In a statement the company said...

Today's triage session concluded with all systems go for a Firefox 4 launch on March 22nd. We will continue to have triage sessions on a daily basis to watch for major issues; however, at this point, we've concluded RC1 will become Firefox 4 final.Firefox is the most popular browser for people who enjoy modding and adding plug-ins to use online.  In this regard it's very different from it's main rival Chrome which focuses on stripped-down simplicity.  Indeed the new IE9 has gone Chrome's way so this could enable Firefox to regain some of the market share it's lost in the last couple of years.

The final version ofd the browser will be available simultaneously for Windows, Mac and Linux and it adds a few features that we've recently seen in other browsers including hardware-accelerated graphics rendering.

It's an exciting time for the web browser industry as the war is well and truly back on after a few years of not very much going on at all.

Firefox 4 Beta 12 has been released (2011/02/26)

Mozilla has just released the latest, and last (as already stated in Firefox 4, The State Of Development), beta of the upcoming Firefox 4 web browser. The beta is currently distributed to Mozilla's worldwide distribution network which means that it may take some time before existing Firefox 4 beta users see the update notification in the web browser.

The website currently links to beta 11 which eventually will be replaced with the download link to the newest beta of Firefox.

The Firefox 4 Beta 12 changelog has been posted and it lists several of the more "popular" improvements in this version of the web browser:

  • Increased performance while viewing Flash content
  • Improved plugin compatibility with hardware acceleration enabled
  • Hovering over links now displays the URL at the bottom of the window rather than in the location bar
  • General stability, performance, and compatibility improvements

One interesting change is that link hover information have been moved back down just above the Firefox add-on bar and almost exactly like Google Chrome and other browsers display those information.

Firefox users who access multimedia contents will benefit from performance and stability gains in the latest beta version.

The full Firefox 4 Beta 12 changelog lists hundreds of changes and fixes, all linking to a Bugzilla error reporting page.

The majority of Firefox ftp and http mirror sites appear to host the new release already. Interested users can take a look at the mirror directory to download the release before the official announcement on the website.

What are the next steps? The team builds the Firefox 4 Release Candidate which is likely to ship in the beginning of March. Eleven hard blockers are left that need to be fixed in the coming builds. The final release will follow suite soon thereafter, provided that no serious issues are discovered in the meantime.

Interested users can take a look at the Firefox 2011 Roadmap Updated, Expect Firefox 7 in 2011 and our guide Firefox 4 Essentials: What You Need To Know Before Making The Switch that prepares users before they make the switch to Firefox 4.

Firefox 4, The State of Development (2011/02/24)

When is Mozilla going to release the next beta of Firefox? When the release candidate and final build of the web browser? News are scarce at this point in time and I will try my best to give you an overview of things to come. The latest public beta version of Firefox 4 is beta 11 which has been available for some time. We knew that the team planned to release at least one additional beta to fix blockers that prevented the release candidate and final release. What we did not know was if that would be the last beta, or if another beta release would follow suite.

Asa Dotzler confirmed yesterday that Firefox 4 Beta 12 "went to builds" on February 22. He furthermore mentioned that "this final (!!!) beta contains fixes to more than 200 hard and soft blockers". The important word here is final which means that beta 12 will be the last beta before the release candidate.

He notes that there is still some patching to do for the release candidate build, with 26 remaining blockers of which half "have patches in some state of evaluation". Mozilla has not yet revealed a release date for the final beta, release candidate and final version of Firefox 4. It is however likely that the beta will be available in the coming days, maybe even today.

I let you know once it becomes available so that you can update your beta versions of Firefox 4 to the latest as quickly as possible. Asa posted an interesting link in the newsletter pointing to Facebook's updated HTML5 games benchmark which sees Firefox in the lead followed by Microsoft Internet Explorer 9 and Google Chrome. Opera and Safari follow with a big performance drop. The reason? Hardware acceleration. The three browsers that lead support hardware acceleration, while the other's do not at this point in time. Opera however has already mentioned that they plan to integrate hardware acceleration in a future version, and that it will support at least the Windows XP browser as well.

Back to Firefox. If the developers stay on track it is likely that we will see a final release of Firefox 4 in the first half of March 2011.

Only one more to go: Firefox 4 Beta 11 is out (2011/02/08)

I'm monitoring the Firefox release ftp server actively for new releases. The long awaited Firefox 4 Beta 11 has just been uploaded to the release server. It means that the Mozilla Firefox development team has finished one of the two remaining beta releases of the Firefox 4 web browser.

Experience has shown that it takes between 12 to 48 hours before the release is officially announced on the Mozilla website. Computer users who are already running Firefox 4 Beta 10 will receive update notifications in the browser at around the same time. Some users may want to try Help > About Minefield to see if the update is already recognized by the browser.

The release notes have not been updated yet, they still link to the release notes of Firefox 4 Beta 10. The release won't offer any new features as it has been primarily been used to reduce the number of existing blocker bugs that need to be fixed fully before the new browser can be released.

The new beta is already on the official release server. We do not link to that server out of courtesy but you can find it easily yourself. You could also try one of the worldwide mirror servers to download the new beta of Firefox early. The mirror servers are currently being populated with the new release and it may take a few hours before they become available there.

Expect Two more Firefox 4 Betas Before Release Candidate (2011/02/03)

It was not clear if Mozilla needed one or two beta releases after Firefox 4 Beta 10 was released last week. The Mozilla Firefox development team is still trying to resolve the remaining severe bugs (betaN hardblockers) that are preventing the release of the next Firefox browser.

Christian Legnitto, the Firefox release manager, made it clear on his blog on February 1 that there will indeed be two additional betas before the development team moves to the release candidate stage. "The current plan is to build [beta 12] when the remaining betaN hardblockers are done" which "is heavily dependent on fix and blocker creation rate" said Legnitto in the blog post.

firefox 4 beta

This basically means that the team did not manage to resolve all serious issues yet. The plan is to release Firefox 4 Beta 11 to the public for testing, work on the remaining issues, build Beta 12 and release it to the public as well.

Mozilla last year postponed the release of Firefox 4 to the first quarter of 2011. Developers hinted at a late February releases which may be in jeopardy because of the recent development. It may be that Mozilla has to postpone the final release of Firefox again, since the team has to work on two beta releases and at least one release candidate before the final version can be build and released. Firefox 4 Beta 11 is expected to be released in the coming days, we keep you posted as usual.

Interested users can download Firefox 4 Beta 10 from the official Mozilla Firefox 4 Beta project page. The beta is offered for Windows, Linux and Mac. It will automatically update to Beta 11 once it becomes available.

Firefox 4 Beta 10 is out (2011/01/26)

Just yesterday we have been talking about plans to accelerate the Firefox development plan, and while the release of beta 10 of the upcoming Firefox 4 browser has nothing to do with that, it shows that the developers are urging to release the final version of Firefox 4 to start working on Firefox 5.

Firefox 4 Beta 10 is not the last beta. Plans are to release beta 11 before the end of this month. If plans go ahead as planned it will be the last beta release before the release candidate.

The tenth beta of Firefox 4 fixes many issues, a complete list of bugs fixed in the release is accessible here.

Notable fixes include improvements in memory usage, compatibility and stability improvements when using Adobe Flash on Mac OS X and support for a graphics driver blacklist to improve stability.

firefox 4 beta 10

The full changelog listing those features and features that have been added in previous beta versions is available here. Downloads are provided on the same page.

Firefox users who are already working with a beta release can use the internal updating mechanism to update their browser to the latest beta version.

It pays to look at the known issues before doing so, especially if its the first time a Firefox 4 beta is installed on the system. Among the issues are problems with Hulu which blocks access to contents because of an "incompatible" browser (caused by a whitelist of user agents which has not been updated to include Firefox 4), slower scrolling in Gmail for some users and problems when downgrading to a beta release before beta 8.

Firefox 4 Beta 9 released, final in February (2011/01/14)

The latest beta of the upcoming Firefox 4 web browser has just been uploaded to the official Mozilla ftp release server. Firefox 4 Beta 9 is currently distributed to the worldwide mirror network to ensure an error free rapid distribution once the official release announcement has been made on the Mozilla website.

It is likely that the announcement will be posted on site later today. Probably the biggest change in the latest beta is the inclusion of the IndexedDB web standard "for the storage of significant amounts of structured data in the browser and for high performance searches on this data using indexes" (via).

Interested users can download the latest Firefox 4 beta from official mirror servers that offer both http and ftp connections.

At least one additional beta will be released before the release candidate stage is reached. Firefox 4 Beta 10 Pre has already been in development for a few days and is available on the nightly servers. The beta is used to reduce the open bug count to zero.

Mozilla plans to release the final version of Firefox 4 in February 2011.

Update: The Firefox 4 web browser is no longer supported or maintained. Mozilla since then has moved to a rapid release process where new stable versions of the browser are released in a six week turn. As of March 2012, the latest stable version is Firefox 11, which will be replaced by Firefox 12 in April. Mozilla furthermore has created a so called ESR version of the browser, which stands for Extended Support Release.

This particular version of Firefox has been designed for businesses and organizations who can't keep up with the new release scheme. Firefox 10 is the first ESR release, which will be maintained by Mozilla for seven release cycles. This basically means a new major version every 42 weeks instead of every six weeks.

Firefox 4 Beta 8 released (2010/12/21)

First spotted by Lee over at the Download Squad, the latest official beta of Firefox 4 has been released by the Mozilla development team responsible for the web browser. The release is currently in distribution which means it may take a while before it becomes officially available on the homepage.

Currently, Firefox 4 Beta 7 is served to downloaders, even on the Beta 8 release notes page which does not feel right to say the least.

But that appears to be a temporary problem only, as downloads will be redirected as soon as the new beta of the Internet browser has been spread to all mirror servers.

Do not expect lots of new features or changes in this beta or coming betas. The team has already stated that Firefox 4 is feature complete which means there will only be changes to the design, and of course bug fixes, loads of them.

The Firefox Sync setup experience has been greatly improved across desktop and mobile devices
Speed, functionality, and compatibility improvements to WebGL
Additional polish for the Firefox Add-ons Manager

Reads the release log. Not a lot to go by to be honest. The interesting part begins below the changes in beta 8, the overall features that have been added to Firefox 4 so far.

A long list, some highlights include:

  • Uses JägerMonkey, a new, faster JavaScript engine, JavaScript speed improvements
  • Certain rendering operations are now hardware-accelerated
  • Responsiveness and scrolling improvements from the new retained layers layout system
  • You can search for and switch to already open tabs in the Smart Location Bar
  • Support for many HTML5 controls and features

There are also controversial features like Panorama or the removal of the status bar and the replacement of it with the add-on bar, or the display of link destinations in the address bar and not the new add-on bar.

Users who do not want to wait for the download links to be updated on the Mozilla website can use one of the release mirrors to download the new Firefox 4 Beta 8 right away.

Firefox 4 Beta 7 Released, Feature Complete (2010/11/10)

The Mozilla team seems to be back on track with the release of the seventh beta of the upcoming web browser Firefox 4. The release marks a milestone in the development as this is the first feature complete release of version 4 of the Internet browser. What does it mean? That the developers won't add new features to the browser. All they do from this point in development on is test, test and test to fix bugs and get the browser ready for a prime time release in the beginning of 2011.

Firefox 4 Beta 7 was originally scheduled for a mid September release which means it is almost two months late. The developers had to fix several blocker bugs that kept them from releasing the new beta on time. Probably the most interesting addition in the beta is the inclusion of the new JavaScript engine JaegerMonkey which speeds up the processing of JavaScript, moving the browser in the region of the fast browsers Opera and Google Chrome.

Several other changes have already been known from previous beta versions, including the removal of the status bar, the addition of the add-on bar in its place and the url bar that now displays link urls when the user hovers the mouse over links on a webpage.

Users who have not tested Firefox 4 release so far will have to get used to other changes as well. This includes the one-button menu, the new tab management feature Panorama, the new add-on and plugin manager and other layout and design changes.

The official Mozilla website has not been updated yet with the download link of the new version. The new beta release is however already available on the Mozilla ftp server and third party download portals such as Softpedia.

Firefox 4 Beta 6 Stability Update (2010/09/15)

Just a week after the release of Firefox 4 Beta 5, the sixth beta of the popular web browser has been released by the Mozilla Firefox development team.

The short time between the two releases already indicates that only a few updates and fixes could have made it into the new release.

Firefox 4 Beta 6 fixes five bugs, one of which a critical stability bug affecting Windows users, another causing rendering errors with plugins affecting Mac OX X users.

Firefox users can take a look at the full bug listing at Bugzilla to read about all fixes in the new beta release of Firefox 4.

The latest Firefox 4 Beta 6 is available for download at the official release notes page.

Preview releases of the next Firefox 4 beta have already appeared on the Mozilla ftp server, which indicates that there will be at least one additional beta release before the first release candidate sees the light of day.

Firefox 4.0 Beta 5 Arrives (2010/09/07)

Today's a big release day over at Mozilla. First it was a new version of the email client Thunderbird that has still not been announced officially. As of this minute, the Mozilla servers are being filled with new Firefox 4.0 Beta 5 releases. The distribution has not been completed yet, and it is likely that it will take at least a few hours before the official announcement is being made over at the Mozilla website.

So what's new in the latest Firefox 4 beta? The add-on manager has been redesigned with a new color scheme. The functionality on the other hand seems to have remained the same. Still no option to search for and install add-ons from the manager.

Hardware acceleration should be enabled by now by default, at least on Windows. A new setting has been added to the browser's options to disable hardware acceleration. you find it in Tools > Options > Advanced > Use Hardware Acceleration When Available.

Finally, the new single menu at the top has been revamped. It opens additional menus when the user hovers with the mouse over an arrow at the end a particular menu item.

The menu is actually not as intuitive as it looks like on first glance, as it happens that submenus pop up accidentally whenever the mouse cursor moves over an arrow icon. Keep in mind though that you can return to the old menu structure, or display it temporarily by pressing Alt.

Firefox 4 Beta 5 will be available later today. Users who do not want to wait that long can download it from the Mozilla ftp server, or wait until the download portals have uploaded the new version to their servers.

Firefox 4 Beta 4 is out (2010/08/24)

Firefox 4 Beta 4 was originally scheduled for a release on August 20, but blocker bugs kept the team from releasing the version on that day. Four days later, and Firefox 4 Beta 4 has finally been released.

The next major iteration of Firefox comes closer to the first release candidate which is slated for an October release date. At least three additional beta releases will follow before the appearance of the release candidate.

Firefox 4 Beta 4 continues where the last beta left off. Firefox Sync is enabled by default, and the Tab Candy, Tab Sets, we mean Tab Groups feature has been renamed once more, at least in this beta build. The feature can now be accessed with the keyboard shortcut Ctrl-Space.

Direct2D rendering is still not activated by default on Windows. Windows users who want to turn the feature on should take a look at Enable WebGL, Direct2D Rendering In Firefox 4 Beta for instructions on how to turn the feature on.

The release notes have not been updated yet, which makes it difficulty to find out if other features have been added or modified in the new release. We will conduct some speed tests right after the publication of this article, and update it accordingly once they are done.


Firefox 4 Beta 4 manages to score a 97 out of 100 in the Acid 3 test, a 200 and 9 bonus points in the HTML5 test. It still lacks behind speed wise both in the SunSpider JavaScript benchmark and the Peacekeeper browser benchmark, but manages to close in slowly but steadily.

The browser overall feels pretty stable after some first testing and shows great progress overall. It won't be as fast as Opera 10.60 when it comes out, but the difference won't be significantly noticeable, and that is all that counts.

Firefox 4 Beta 4 has not officially been announced yet. The beta is as usual available on the official Mozilla FTP server. Except an official announcement later today.

Firefox 4 Beta 3 Arrives (2010/08/11)

Firefox 4 Beta 3 is currently in the distribution phase and will be available shortly at the official beta download page for all supported operating systems and languages. Several download portals, including Softpedia, are already offering the English language version of Firefox 4 Beta 3.

The release notes have not been updated yet, which means that the official Firefox website does not offer any information at this moment about changes or additions in this beta of Firefox.

Lee over at the Download Squad however was able to discover some of the changes. The biggest additions according to him are the addition of multitouch support on Windows 7, and improvements to the execution time of JavaScript code in the web browser.

Mozilla expects to release two additional Firefox 4 beta versions before the release candidates and final versions of the browser. Firefox users should mark the day of the release of the fifth beta of the browser, as it will introduce Mozilla 2, the "most comprehensive iteration (since its creation) of the overall platform on which Firefox and other Mozilla products run". While some changes have been incorporated into Firefox 3 releases, the major changes are slated for a Firefox 4 Beta 5 release.

Mozilla designer Brendan Eich mentioned Mozilla 2 in 2006 for the first time, which was originally planned to be released in 2008.

Mozilla 2 means among other things a chance to break frozen API compatibility, which removes constraints on the current architecture and allows us to eliminate old APIs and their implementations, renew and improve the APIs and code we want to keep, and realize significant runtime and code size wins. For instance, we can get rid of RDF, which seems to be the main source of "Mozilla ugliness" humorously decried by Steve Yegge.

For Mozilla 2, we will have a JIT-oriented JavaScript VM (details soon) that supports the forthcoming ECMAScript Edition 4 ("JS2") language. Among the desirable characteristics of this VM will be a conservative, incremental garbage collector (GC). If it makes sense, we can use this GC module to manage DOM object memory instead of using XPCOM reference counting. We can use its conservative scanning code to assist in cycle collection. And we can JIT calls directly into DOM glue code entry points (provided no JS mutation has overridden a method property value), bypassing the powerful but relatively slow typelib-based dispatching machinery of XPConnect.

This will kick Ajax performance in Firefox up a notch or three.

So Mozilla 2 is not just about simplifying APIs, removing old code and XPCOM overhead, and making the source code more approachable. It's also about material improvements to program security, which is inherently weak in all browsers implemented in languages such as C and C++. Security requires defense at every level of abstraction, from high-level JS that enforces confidentiality properties, down to buffer manipulations that should be provably memory-safe.

Firefox users can expect lighter code, and better overall performance of the web browser. The platform goals outline some of the goals the developers have for Firefox 4.

Goals include

  • to improve the JavaScript performance to come near or even with Chrome 5
  • hardware acceleration of the user interface, video, and other HTML and SVG content
  • Fully support the WebGL 1.0 spec, with support turned on by default in a Firefox 4 beta on platforms that support OpenGL or OpenGL ES.
  • Accelerate all drawing on Windows Vista and Windows 7, on compatible hardware, by shipping the Direct2D Cairo backend in a Firefox 4 beta.
  • Ship WebM with performance and stability equal or better than Flash on Youtube
  • Close the performance gap between Firefox and Chrome on the "Click Preferences *" tests in the Zimbra performance test harness, 30+% speedup from end of Q2.
  • Improve user privacy by reducing the ability of sites to fingerprint individual users, and improve user control and privacy of cookies.
  • Performance goals for reference system: Dell Optiplex 760 (Intel Core2 Duo) Windows Vista. Baseline: Chrome 5.0.375.55.
    [ON TRACK] SunSpider: 300-375ms.
    [ON TRACK] V8 Score: 3500-5000.
    [ON TRACK] JSNES: 60fps.

The coming months will be exciting for Firefox users.

Firefox 4 Beta 2 Released, App Tabs included (2010/07/28)

Mozilla has released Firefox 4 Beta 2 yesterday, a new beta version of the upcoming Firefox 4 web browser. The new version can be downloaded from the release notes or official beta download page. It is as usual available for all supported operating systems (Linux, Mac, Windows) and languages.

The "big" new feature in Firefox 4 Beta 2 is App Tabs, which resembles Google Chrome's Pin Tab feature. Every tab in Firefox has a new option on right-click to convert it into an App Tab. Those tabs are reduced to their Favicon and placed on the leftmost side of the tabbar.

Mozilla developers have created a short video to demonstrate the new App Tab feature

A new page loading animation has been added as well, the favicon of sites in the tabbar is replaced with a loading animation, which switches back to the website's favicon once the page has loaded fully.

The release notes contain additional changes and feature descriptions, including:

  • Tabs are now on top by default on Windows and OSX - Linux will be changing when the theme has been modified to support the change.
  • Responsiveness and scrolling improvements from the new retained layers layout system.
  • JavaScript speed improvements due to engine optimizations.
  • You can search for and switch to already open tabs in the Smart Location Bar
  • The stop and reload buttons have been merged into a single button on Windows, Mac and Linux.
  • The Bookmarks Toolbar has been replaced with a Bookmarks Button by default (you can switch it back if you'd like).
  • Full WebGL support is included but disabled by default at this time
  • Native support for the HD HTML5 WebM video format.
  • An experimental Direct2D rendering backend is available on Windows, turned off by default.
  • More responsive page rendering using lazy frame construction.
  • Link history lookup is done asynchronously to provide better responsiveness during pageload.
  • CSS :visited selectors have been changed to block websites from being able to check a user's browsing history.
  • New HTML5 parser, Support for more HTML5 form controls.

Firefox 4 Beta 2 reaches the same score in the HTML5 browser test as the last beta. The browser scores 97 of 100 points in the Acid3 test, but drops 200 points in the Peacekeeper benchmark when compared to the performance of Beta 1.

Enable WebGL, Direct2D Rendering in Firefox 4 Beta (2010/07/28)

The latest beta of Firefox 4, and actually several previous versions of Firefox as well, have features included that are disabled by default, mostly because they have not been tested enough to enable them for all Internet users by default.

If you have read the Firefox 4 Beta 2 release notes you may have noticed that they explicitly mention two features that are included but disabled in the beta release, specifically:

  • Full WebGL support is included but disabled by default at this time
  • An experimental Direct2D rendering backend is available on Windows, turned off by default.

Both features can be enabled in the about:config configuration settings of the Firefox browser.

How To Enable WebGL In Firefox

What it does: "WebGL enables web content to use an API based on OpenGL ES 2.0 to perform 3D rendering in an HTML canvas in browsers that support it."

Demo Pages:


webgl demo
webgl demo

Escher Droste

Enabling WebGL:

Type about:config in the Firefox 4 address bar, and enter to load the configuration page. First time users need to accept the warning message before they can continue.

Filter for the term webgl which should display four results. Locate webgl.enabled_for_all_sites and double-click the entry to set it from false to true. This enables WebGL in Firefox. Restart the browser to apply the changes.

How To Enable Direct2D Rendering In Firefox

What it does: You should enjoy your new browsing experience, in most cases you should have a noticeably faster and more responsive browser, particularly when using graphically intensive websites (not using flash, which will still be slow) (via)



Enabling Direct2D:

It has to be noted that Direct2D is currently only supported by Windows 7 or Windows Vista, with Windows 7 being the recommended operating system. Firefox users should also have a DirectX 10 compatible video card, even though DirectX 9 cards may work but with significantly lower performance gains.

To turn on Direct2d, complete the following steps:

  • Enter 'about:config'
  • Click through the warning, if necessary
  • Enter gfx.font in the 'Filter' box
  • Double-click on 'gfx.font_rendering.directwrite.enabled' to set it to true
  • Below this, right click and select New > Integer to add a pref setting
  • Enter 'mozilla.widget.render-mode' for the preference name, 6 for the value
  • Restart

And that's how you enable WebGL and Direct2D in the Firefox browser. Have you been experimenting with those parameters? Let us know in the comments.

Firefox 4.0 Beta 1 is out, download now (2010/07/06)

The Mozilla developers have released the first beta of the long awaited Firefox 4.0 web browser. Regular readers might know that this version was offered as Firefox 3.7 previously and has now been renamed to Firefox 4.0, a release of the final version is expected at the end of this year.

Firefox 4.0 continues where Firefox 3.7 has left off. It sports a new interface design, something that many veteran Firefox users may have problems adopting with.

Browser tabs are now located on top of the address bar by default with the option to revert the changes so that the interface resembles the old Firefox design.

firefox 40

A second major change is the addition of the Firefox button, which will be shown if the user decides to hide the menu bar in the browser. This option looks similar to the one-button menu option of the Opera web browser.

Firefox 4.0 comes with a new add-ons manager, which is not completely available in the beta release. It is for instance not possible to search for and install add-ons directly from the manager.

The HTML5 capabilities have been improved, with support for web standards such as WebM video and other HMTL5 related features. Firefox 4.0 now scores 189 and 9 bonus points out of 300 in the HTMl5 test, an increase of 50 points and 5 bonus points over Firefox 3.6.4.

Firefox 4 still lacks behind speed wise in most browser benchmarks but it looks like the developer's have concentrated on interface and feature additions so far.

This version features protection against an attack known as CSS fingerprinting which uses lists of popular websites to determine if a user has visited them in the past.

Interested users can watch a WebM video about the new release, read the release notes, take a look at the first run page or download versions for Mac, Windows and Linux below.

Thanks HDW for the tip. Have you tried the browser already? Let us know what you think about it in the comments.

Firefox 4 : Find out what is new
I have followed the development of Firefox 4 from pre-beta to the final release, and have to admit that it was not always a pleasant ride. It looked in the beginning as if the developers planned to make changes for the sake of changes, and not because they made sense or were demanded by the majority of the Firefox community.

    Since I’ve rarely wanted to transfer more than one tab between browsers, I’m not inclined to install another extension just for that — especially one that (according to your description) closed all my tabs in the process. In the past I’ve just copied and pasted the URL, but (even for just one tab) that is a little tedious.

    I just tried an interesting little experiment, with a useful result. (I did this on my Mac, but I’m guessing it would work on other platforms too.) I’m reading this article in Firefox, so I opened a new blank window in Chrome. At the top of both browser windows, at the far-left end of the URL bar, there’s a little icon of the letter “i” in a circle. (If you hover over it in Firefox, it says “Show site information”; in Chrome, hovering it says “View site information” — that’s the icon I’m talking about.)

    I simply dragged the Firefox “i” icon from the top of this page, into the Chrome window — and this page loaded in Chrome! It worked! Then I tried something just a bit trickier, in the other direction — I first (from a bookmark) loaded into Chrome a page from my local web-development server (i.e. not online)… then dragged the “i” icon from the Chrome toolbar into this Firefox window — and it worked then too!

    So, although I have no interest in the OneTab extension, I just learned something useful! I hope other people find this trick useful too. (Later I’ll try it in Safari — maybe it works in every browser?)

        This comment actually does make a lot of sense, and I am actually searching for this. Some people do NOT want websites to be (badly) translated, so they never use such a feature. The things is, every time I visit a non-english website this annoying menu pops up, and the button is another element in the URL bar cluster of useless unused features. I do not want to add all languages to a “do not translate” list, instead I want a “hide button” or “disable translations completely” setting.

  9. Mystique said on August 23, 2023 at 11:11 am

    This isn’t great but it might help people that have moved from chrome to firefox to some extent. I can’t tell you the amount of time I have seen people complain that a certain extension they use on google is not available and the only thing holding them back from moving over when they are actually wrong and the very same developer has a Firefox version also. I would always encourage manually looking as there are always hidden gems.

    In regards to the website I have reached out to Martin personally and to his credit he replied very quickly. He has informed me that they are aware of the problems and are attempting to fix it.

    Martin is no longer involved in the technical management of the site so I imagine if we want to ask someone then our comments would perhaps be better directed towards Softonic.

  10. John G. said on August 23, 2023 at 11:39 am

    I don’t understand what is happening here with the comments. The counter shows zero comments and then inside there are some comments from older dates even since years. And mostly of them are non related by the way with the article. So sad what’s going on and nobody is still fixing it. :S

    “Import Chrome extensions” …. (by installing comparable Firefox extensions) … (for a small number of extensions).”

    What a bunch of bogus PR spin. Someone who liked uBlock Origin on Chrome could already install it just fine on Firefox with a couple of mouse clicks. This just adds extra unnecessarily complicated steps to something that was already dead simple, all in order for Mozilla to claim fake one-to-one compatability that doesn’t actually exist.

  12. Ray said on August 23, 2023 at 9:57 pm

    It would be interesting if Firefox could install Chrome Addons directly from the Chrome Web Store. Although there would probably be some incompatibility, perhaps there’s a shim to translate some Chrome-specific WebExtension APIs over to Firefox. Microsoft Edge can install extensions directly from the Chrome Web Store, but Edge is using the same Blink web engine as Chrome so that makes things easy.

    Don’t really care about importing as I never use that feature.

  13. Rex said on August 24, 2023 at 11:50 am

    Just retire Gecko and join the Blink bandwagon already, Mozilla. Then you can guarantee 100% Chrome extension compatibility! /s

    I tried Firefox Translate, but it doesn’t do Chinese or Japanese, and that’s a deal-breaker for me. I uninstalled it and am sticking with the Google Translate extension.

  17. ECJ said on August 27, 2023 at 7:07 pm

    “…Vivaldi and Brave use self-hosted solutions, which still require connections, but offer better privacy than an integration of Google Translate or other third-party translation services would offer.”

    While I like Brave as a browser, their translation “solution” just plain sucks. I’d rather have the data sent to Google or Bing, than have a translate feature that just doesn’t work properly. Not only is it not possible to select just a section of text to translate, but to make it worst, most of the time translating the whole page in Brave is either really unbearably slow, or more often than not, it just won’t translate the page at all and displays a “This page couldn’t be translated” error. It’s pretty pointless if their users need to keep using something else to translate pages and have to give up their privacy anyway.

    The native translate feature in Firefox sounds like a much better solution than what Brave use.

    I think for now every time I comment on an article I am going to put the title of the article and/or the URL of said article because I am seeing my own comments which are from another Firefox related article but not exactly this one.

    In regards to this website Martin does not have administrative access to the back end of the website. It would fall on softonic international to fix it now which seems to be of very low priority.

    This might be the straw that broke the camels back for ghacks which is a shame because it had many good comments and articles that go way back. Moving away from it would suck.

    It’s exciting to hear that Mozilla is actively working on a design refresh for their Firefox web browser, internally referred to as Photon. The last major redesign, known as Proton, was introduced in Firefox 57 back in November 2017. Since then, Mozilla has made some interface changes, including the controversial address bar overhaul in Firefox 75 Stable.

    While specific details about the design refresh are currently limited, Mozilla has created a meta bug on Bugzilla to track the changes. Although no mockups or screenshots have been shared yet, the bug names provide some insights into the elements that will receive a refresh, such as the address bar, tabs bar, main menu, infobars, doorhangers, context menus, and modals.

    The new design is scheduled to be released in Firefox 89, which was initially planned for a mid-2021 release, specifically May 18, 2021. However, as development work is still ongoing, there is a possibility of a delayed release.

    1. TelV said on September 13, 2023 at 11:58 am

      @ Zibtek,

      I’m already using Photon on Floorp which is a fork of Firefox. Here’s a pix of what it looks like: I enabled the menu bar at the top, but you can turn it off if you don’t like it.

      Floorp is a Japanese browser based on FF102. I’ve been using it as my default browser ever since ‘owl’ pointed it out on the Ghacks site last year (or was it this year, can’t remember exactly when). In any event it contains many more enhancements than the vanilla version of Firefox. It also comes with searXNG search engine in the list of search engines provided which saves having to install it yourself.

    My comment is regarding the following,
    Article title:
    Mozilla patches critical WebP security issue in Firefox and Thunderbird

    Indeed, today, those patch versions were applied through automatic updates.
    However, since I had disabled the “WebP” function, I was not interested in that topic (Google, etc.).

    Regarding Thunderbird:
    Today finally,
    My Thunderbird 102.14.0 (en-US) was updated with “Thunderbird 102.15.1 (x64)” through the automatic update feature.
    By the way,
    Naturally, it will not be automatically updated to 115 (Supernova).

    it is clear from Bugzilla that the bug fixes related to migration from 102 to 115 are not complete, so existing users of “102” should refrain from manually updating to 115.

    Betterbird has been released 115.2.1-bb11 (12 September 2023) . Betterbird make Thunderbird a faithful upstream.

    What happened to gHacks? When the site was bought out, Martin assured us it wouldn’t go downhill and he’d maintain editorial control, but the AI-written articles are ruining the quality of the site. I’ve been tempted to drop the site from my RSS reader because of this. Is there an RSS feed with only the human-written articles? Individual feeds for each author isn’t a good solution.

    If anyone was unaware you should download the extension “Don’t Accept WebP” regardless of the patch. WebP is absolute trash that is unnecessary and clearly an issue. I would rather my images be in their native format and not some recompiled trash such as WebP.

      I agree, this is so atrocious – most of the time you can even tell by the URL what format the original image was in – this “reconvert-on-the-fly” nonsense is terrible – but especially so when you’re converting a lossy format, which should be avoided as often as possible.

      Sometimes you can edit the image URL to get it to send the right image, unfortunately “don’t accept WebP” doesn’t always work – but that’s why they offer a built in conversion, I suppose.

    “important address bar change” alright calm down… lol

    I have gotten rid of the stupid shield and the “not secure” box, and have it set up so that it always displays the full URL (I think…?).

    In a perfect world, it should just always show the full url, no icons, or emojis, or anything like that.

    “Users may want to know why Firefox is no longer displaying https:// in the address bar” I’ll bet nobody will notice anything – apart from a select few autists like myself who customise everything and don’t like change.

      “Users may want to know why Firefox is no longer displaying https:// in the address bar”

      Why, I don’t know either (a breeze of madness or is it of love in the air), but there’s an about:config to handle that as well (Firefox) :

      // display all parts of the url in the location bar (do not trim)
      pref(“browser.urlbar.trimURLs”, false); // Dfault=true

    Firefox is always copying whatever Chromium does… it is like they are a Chromium browser without the name and having trouble rendering many websites. In fact, it is like they are getting 400million just for existing and adopt anything Google releases or does, like web extensions, widevine, safe browsing and then visual changes like this.

    I like how some people think there is a choice, and the choice is better than the leader… while still failing at basic stuff.

    Article: Firefox 119 will launch with an important address bar change

    Just one thing regarding the URL bar as it looks like now in latest Firefox, the relatively new feature where some extensions would add their icon inside the URL bar, how bad can it get?
    ps. uploaded same pic to several links just to make sure some will work.

    (For those who can’t see the pic it’s a snapshot showing a URL bar full of extensions, and also Firefox own built in icons that would appear inside the URL bar depending in some cases on which type of website is being viewed, there’s no space left for the actual thing the URL bar is supposed to view, namely the URL address itself)

    Yes, I have several extensions on the toolbar, but the menu bar is pretty full and I want to keep some on the toolbar too, and usually Firefox would also push excessive extensions behind a drop-down menu for access to them as well, but as it looks like now the URL bar is given too little space priority, or is there a way to restrict to a minimum URL bar size?

      You can modify Firefox with a “profileFolder/chrome/userChrome.css” file:
      /* */
      /* */
      @import url(urlbar_info_icons_on_hover.css);
      @import url(page_action_buttons_on_hover.css);

    While that small change would make sense as standalone, it’s unfortunately done in a context where Google (and thus Mozilla) wants to get rid of the URL ultimately and just display search engine data on that bar, going on with that trend of the browser only being a search engine carrier.

    Were users forced to use the same account for different Mozilla products ? Maybe those who want their news reading habits to be tracked and monetized by Mozilla Pocket do not want their e-commerce habits to be tracked and monetized by Mozilla Fakespot under the same identity ? This is really starting to look like a Google account. When I think that this Firefox account thing more or less started with just an end-to-end encrypted sync service where Mozilla could not access the data. Now they use accounts to monetize user data. Sigh.

    There are probably still drones haunting the web claiming the highly repeated lie that “Mozilla does not even have user personal data” (meaning they only monetized the fuck out of every possible piece of sensitive private user data under other forms, without the risk of breaching GDPR). Well, sure they have, lots of that too.

    “users who signed-in using Google or Apple credentials”

    Wait, what ?
