Firefox 35 Find out what is new

Firefox 35 is the latest version of the web browser that is made available to all Stable channel users as of January 13, 2015.

All other Firefox channels, that is Beta, Aurora, Nightly and Extended Support Release, are also updated to the next major version which in this case means Beta 36, Aurora 37, Nightly 38 and ESR 31.4.

You can find out which version and channel you are running by typing about:support in the browser's address bar and hitting enter.

The page that opens up displays the information under Application Basics.

Firefox 35 Download

The official release date of Firefox 35 is January 13, 2015. Firefox releases are always pushed to the official Mozilla ftp server before the official release data and distributed to mirror sites around the globe to ensure that the update runs flawlessly for all users of the browser.

While it may be tempting to download that version, last minute changes may require that another build gets released as the final version. It is therefore best to wait until the release is announced officially by Mozilla.

Most Firefox users will receive the update via the browser's built-in update module. Users who prefer to download it instead can do so on the official Mozilla website.

Firefox 35 Changes

Firefox 35 ships with new and improved features. While that is the case, it appears to be a minor release feature-wise both on the desktop as well as on mobile.

Firefox Hello with room functionality

Rooms extend the functionality of Firefox Hello, the real-time video and audio chat module of Firefox that Mozilla introduced in Firefox 34.

It works similar to chat rooms that persist even if the initiator of a connection closes Firefox or the Hello module.

Rooms are limited and not comparable to IRC chat and other chat rooms where dozens or even hundreds of users communication with each other.

From initial tests, it looks as if rooms are limited to 2 participants.

Additional information about Firefox Hello are available on Mozilla Support.

HTTP Public Key Pinning Extension implemented

Public Key Pinning was introduced in Firefox 32 on the desktop and in Firefox 34 for Android. The security feature links specific domains and services to Certificate Authorities (CAs) so that they are used instead of authorities that are not mentioned.

The Public Key Pinning Extension provides site owners to do the same on their end. It allows them to list acceptable Certificate Authorities that browsers should use during connection to reduce the impact of compromised Certificate Authorities.

Public Key Pinning Extension requires an initial connection to the site in order to get the pinset from it which it wants the browser to use in future connections.

Other Changes

  • Built-in support for H264 (MP4) on Mac OS X Snow Leopard (10.6) and newer through native APIs
  • Tools menu links to Firefox Marketplace, icon also added.
  • New Search UI enabled for more locales.
  • Tile rendering on Os X.
  • Improved handling of dynamic styling changes to increase responsiveness.
  • Plugin Finder service has been shut down [Bug 836415]
  • Fixed: reduced resource usage for scaled images

Side Note: If you are using the new search interface introduced in Firefox 34, you will notice that it is still not possible to rearrange search engines. It is possible to change the order of search engines now. You need to open the Search Options for that and use drag and drop operations to reorder the search engines. Check out this guide if you want to restore the old search interface in Firefox.

Developer Changes

  • Support for CSS Source Maps enabled by default. Allows you to edit preprocessor files like Sass, Less or Stylus in Firefox instead of CSS generated from those files.
  • Access Show DOM Properties from the element context menu.
  • CSS Filters enabled by default.
  • WebSocket available in Workers.
  • CSS Font Loading API support. [Bug 1028497]
  • Resource Timing API implemented. [Bug 1002855]
  • The network.websocket.enabled preference has been removed.

Firefox 35 for Android

If you are using Firefox for Android you will notice that the browser requests permissions to access Wi-Fi connection information which it did not require before.

The permissions are used to improve the browser's location-based service according to Mozilla.

  • Bing Search uses HTTPS now.
  • Geolocation service sharing Wi-Fi and cellular signals now with Mozilla if enabled by the user.
  • Android Download Manager is used to keep track of downloaded files.
  • Network error pages show search dialog now.
  • HTTP Public Key Pinning Extension support.
  • Files downloaded in private browsing mode are not listed in the download manager.

Security updates / fixes

Security updates are published after the release of the browser. We will add those once they become available.

  • MSFA-2015-09 XrayWrapper bypass through DOM objects
  • MSFA-2015-08 Delegated OCSP responder certificates failure with id-pkix-ocsp-nocheck extension
  • MSFA-2015-07 Gecko Media Plugin sandbox escape
  • MSFA-2015-06 Read-after-free in WebRTC
  • MSFA-2015-05 Read of uninitialized memory in Web Audio
  • MSFA-2015-04 Cookie injection through Proxy Authenticate responses
  • MSFA-2015-03 sendBeacon requests lack an Origin header
  • MSFA-2015-02 Uninitialized memory use during bitmap rendering
  • MSFA-2015-01 Miscellaneous memory safety hazards (rv:35.0 / rv:31.4)

        Then switch to the ESR version if you don’t want to deal with more frequent updates. Nobody’s twisting your arm to use the version with frequent updates.

          Excellent decision. Version 10 was the first release that I ran in ESR edition.

      Firefox 35 seems here slightly more snappy, slightly faster. But this may very well be my imagination.
      A minor update indeed as stated in this article. Otherwise 35 reminds me the happiest years of my life (when 34.05 sounded less adequate).
      And the beat goes on.
      Thanks for this regular appointment to Firefox updates as well as to others. What’s new, what’s up? I know I’ll always have a full detailed article over at Ghacks’ (sounds like the latest bar in town!).
      I appreciate it, we all do.

        I don’t think it’s your imagination; I noticed it too, both on Windows and Android. Probably due to ‘Improved handling of dynamic styling changes to increase responsiveness’ and ‘reduced resource usage for scaled images’.

      About your note that you cannot rearrange search engines…
      I’m currently on Beta, which is still 35, and can open the Search tab in Options and drag the engines up and down in the list and this new order is reflected in the search interface. So it looks like they did fix this.

      On a side-note of my own, they do have a fix coming for being able to change your default search engine directly from the search bar.
      Oh, and they fixed the bug where right clicking on the bar would have the context menu behind the new interface.

      Looks like I’ve spoken a bit too quickly.
      I just realized Firefox 35 has rendered two add-ons totally ineffective : Paste Email Plus and disallow Script Button. The former kept its icon on the toolbar, the latter vanished. Both are K.O.
      Reverted to Firefox 34.05 until I find out the why of the how.
      First time I notice this sort of problem.

        Lots of problems with Firefox 35:

        – Firefox buttons in about:home don’t work
        – Adbock Plus/Edge stopped working
        – Firefox asks to restart when enabling/disabling restartless addons
        – Lots of addons icon disappeared from toolbar

          I can’t confirm any of your problems. So it seems that either your Firefox profile is broken or one of your add-on causes the problems.

          I’m also on 35 and don’t experience any of these issues.
          As Sören mentioned, an addon that hasn’t updated it’s code properly can break things. Try restarting with addons disabled (under the Help menu) to see if that makes a difference.
          Try creating a fresh profile (for testing) using the profile manager. If things work as expected, consider doing a reset which will import your primary data (open tabs included) into a fresh profile – seems like there may be corruption in your profile in this case.

          P.S. Do make sure to simply restart your browser first on the chance that this is a one-off issue.

          Firefox 35 has broken many of the add-ons I use (Adblock Plus, Cleanest Addon Manager, Ghostery, Restartless Restart), and it also causes session data (currently open tabs) to be lost when restarting the browser. Everything worked fine in Firefox 34 just before updating to v35.

          Thankfully, the Adblock Plus forum (https://adblockplus.org/forum/viewtopic.php?f=1&t=27375#p114744) has figured out the issue. Apparently, the about:config preference “dom.indexedDB.enabled” has been changed in Firefox 35 to apply to websites, add-ons, and session data instead of just websites, so setting it to “false” causes many add-ons to stop working. Therefore, setting it to “true” then restarting Firefox fixes the problem (all broken add-ons now work and session data is retained after future restarts).

          This will be fixed in the release/stable version of Firefox 37 in April (https://bugzilla.mozilla.org/show_bug.cgi?id=1079355). Unfortunately, until then we’re stuck with a minor decrease in privacy by having to enable that pref.

          TLDR version: fix the problem by entering “about:config” (without quotes) in the URL bar, searching for “dom.indexedDB.enabled” (without quotes), double-clicking on it until it’s set to “true”, and restarting Firefox

          P.S. ghacks is a great website, Martin. Thanks a lot for all your work.

      Someone last week suggested SeaMonkey. I tried it again and I’m pretty happy with it this time. I’ve already contributed some work and I hope the project starts to gain more support from recent Firefox and Opera defectors.

      You can convert many extensions to work with SeaMonkey using this page: http://addonconverter.fotokraina.com/

      Still no MSE work being done. I guess it’s still 720p max Flash only videos for me until the bug-ridden mess gets sorted out ten years from now.

        To say that it has not landed yet is not to say that there is no work being done. They’re working on it quite a lot actually.
        Sounds like they may skip some normal test releases in order to get it released sooner:

          I wrote the previous after having read an open thread on their development tracker (or bug tracker or… some official “tracker” of theirs) which seemed to indicate that a grand total of two people were focusing on that end of development for it, with the last recent post being almost a year old.

          At this point I’m not sure if I want it fast and done or slow and free of the ridiculous bugs that shouldn’t have been there even as long as they have now.

        By now Update available is stated but, having not installed the automatic update and clicking on the Firefox home link to download 35, it is still 34.0.5 which is proposed.

      Australis-fear can be solved by enabling the old menubar: Alt > View > Menubar. Throw in a bit of UserChrome.css and/or a Persona you’re good to go: http://i.imgur.com/Iapx5bu.png

        Do you use Ghostery? Empty preferences are a known bug of Ghostery.

      you missed some features:

      New search UI improved and enabled for more locales
      Use tiled rendering on OS X
      Access the Firefox Marketplace from the Tools menu and optional toolbar button
      Improved high quality image resizing performance

      Even some developer changes:

      Network Monitor: New request/response headers view (http://hacks.mozilla.org/2014/12/pseudo-elements-promise-inspection-raw-headers-and-much-more-firefox-developer-edition-36/)
      Added support for the EXT_blend_minmax WebGL extension

      It’s probably because used the beta release notes to construct this articles.

      I too am struggling to use many previously working websites. Just tried RedSpottedHanky – would not accept payment, Moved to tthetrainline.com which did process OK and they had posted a message to FF users but unfortunatley I did not get to read it!!

      Come on Mozilla – let’s get back to helping your user base instead of alienating them!
