Mozilla released Firefox 110.0 Stable for all supported operating systems today. The new Firefox release introduces GPU sandboxing on Windows, improved importing of user data from browsers, performance improvements, and a lot more.

All Firefox development channels and Firefox for Android receive updates at the same time. Firefox for Android is also updated to version 110. Firefox ESR, the Extended Support Release, receives an update to version 102.8. Firefox Beta, Developer and Nightly editions are moved to version 111 and 112 respectively.

Executive Summary

  • Firefox 110 continues to support Windows 7 and Windows 8.1, even though both operating systems are no longer supported by Microsoft.
  • The Firefox update addresses 19 different security issues that are rated high or lower.

Firefox 110 download and update

You can check the installed version by selecting Menu > Help > About Firefox. Firefox 110 is available already and it should be installed automatically on most systems. Users may speed up the update on desktop systems by opening the About Firefox page.

Here are the official download locations:

Firefox 110.0 new features and improvements

Firefox 110 is a big update that introduces several changes and improvements.

Windows security improvements

Firefox for Windows supports GPU sandboxing now in the latest version of the browser. GPU sandboxing isolates the process of the graphics processor to neutralize malware attacks or reduce the impact that they can have on the system.

Firefox users may load about:support and check the GPU Process Sandbox Level value there to find out if it is enabled. Any value above 0 means that the sandbox is active.

The second Windows-specific feature enables users of the browser to block third-party modules that inject themselves into Firefox. The main idea behind the feature is to block third-party modules that cause issues, such as browser crashes.

To use the feature, load about:third-party in the Firefox address bar. Firefox lists all third-party modules on the page. A click on the "block this module" button prevents the module from being loaded in Firefox in the future. A restart is required to block the module. Modules may be unblocked at a later point by repeating the process.

Mozilla Firefox highlights modules that caused Firefox or some of its components to crash on the page. The following help page walks you through the process in detail.

Other changes and fixes

  • Firefox users may import data, bookmarks, history and passwords, from Opera, Opera GX and Vivaldi next to Edge, Chrome and Safari starting with this release.
  • Firefox users on macOS and Linux have Canvas2D GPU acceleration enabled now.
  • WebGL performance improvements on all desktop operating systems that are supported.
  • On Windows 10 and 11, overlay of hardware-decoded video with non-Intel GPUs us now supported, which improves video playback performance and video scaling quality.
  • The keyboard shortcuts Ctrl-Backspace and Ctrl-Delete may be used to clear date, time and datetime, local input fields. (Mac users need to replace Ctrl with Cmd).

Developer changes

  • Container queries and container query length units are now supported by default.
  • The color-gamut media query is now supported.
  • The list attribute is supported in <input> elements with type="color" on Windows and Linux.
  • Serialization of native Error types now includes the stack property in workers when using Worker.postMessage() and structuredClone().
  • The midi permission of the Permission API is now supported.
  • ReadableStream now supports asynchronous iteration over the chunks in a stream using the for await...of syntax.
  • Various WebDriver BiDi improvements.

Enterprise changes

Mozilla supports downloading language packs now using the same syntax as downloading Firefox. This bug report has details on the feature. Basically, what it means is that it is now easier for Enterprises to install language packs via a policy.

Firefox supports the DisableThirdPartyModuleBlocking policy now, which prevents users from disabling injected modules on the about:third-party page of the browser. This does not apply to ESR.

Security updates / fixes

Firefox 110 addresses 19 different security issues in the web browser. The maximum severity of a vulnerability is high, which is second to the highest severity rating of critical.


Firefox 111 Stable and Firefox 102.9 ESR will be released on March 14, 2023.

    Well, I’ve been using the Help > About to update since about 102, probably earlier. I decided 110 would be a good time to start from scratch. So installed 110.0, set my settings, bookmarks, passwords.

    Everything good until I added extensions (i.e. AdGuard, Dark Reader, KeePassXC) and NOT ONE of the Toolbar icons (shortcuts, whatever they’re called) will show up. And they’re not in Customize or Overflow, where they wouldn’t be anyway. Happens if I add directly from the web page or using the “find more” in about:addons.

    However, when I add a recommended extension, like Privacy Badger, the icon shows up.

    Just for grins, I tried adding the extensions in a default profile – didn’t show up either.

    Well, that’s what I get running a .0 version. But expectations in .0.1 might not fare better.

    1. Haakon said on February 17, 2023 at 11:16 pm

      Forgot to try this one:
      Set extensions.unifiedExtensions.enabled from true to false.
      Restart FF.
      Add extension.
      In Customize Toolbar, drag icon from Overflow to Toolbar.

      And I stand corrected… Icons can be in the Overflow.

      That said, in 109 and previous, the pref was always True.

    Was the below cache problem fixed in FF 110?


    Firefox 109.0 broke clearing Cache on shutdown… great. :/

    Since updating I was noticing a ton of junk files being created when closing the browser.

    (The folder with the junk files in question resides in your ProgramData folder and named “Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38”.)

    Well after doing some digging it seems to be 100% related to clearing Cache on shutdown.

    Waiting for new LibreWolf release.

    If I were a Firefox user, I would be able to use the WebGL improvements, since my Logos Biblical studies website uses it heavily to show the different Bible and commentary texts. Maybe I’ll have to try it out.

    19 security problems is a lot, Google Chrome would be proud of a number that high. I thought Mozilla was re-writing all their code with their super-secure-never-fail programming language and getting rid of all future security issues.

    1. Anonymous said on February 15, 2023 at 6:23 pm

      So many Chrome fanboys here.

    2. Iron Heart said on February 15, 2023 at 8:34 am

      Yeah 19 security issues in Firefox is a high number, it seems like each remaining user discovered one security flaw.

      1. Sebas said on February 16, 2023 at 7:33 am

        @Iron heart Really you made my day :):):)

      2. @Sebas said on February 16, 2023 at 2:48 pm

        How lucky are those who are so easily amused!

      3. Marco said on February 16, 2023 at 12:20 am

        You are not Iron Heart. The real Iron Heart is a fanatic and fanatics don’t have sense of humor.

      4. McCormacksAlgorithm said on February 15, 2023 at 6:42 pm

        The more it becomes like Chrome the more flaws it has. Quite logical. I see the trend.

        Haaaaa! Repeated knee slapping here

  6. DeletethisifyouareCCP said on February 15, 2023 at 2:35 am

    well quality posts these day kinda become unstable with influx of new authors and sometime overlap of covered topics. Guess Ghacks is going down.
    I will just stick with phoronix.

  7. VioletMoon said on February 15, 2023 at 1:58 am

    “Sandbox” was on version 109 and set to shown parameters in article—quite refreshing, thanks!

    “Firefox lists all third-party modules on the page. A click on the “block this module” button prevents the module from being loaded in Firefox in the future.”

    I may get in trouble here; I “blocked” several modules that were duplicates. No mention whether to do that or why it may have occurred.

    Restart worked.

    Bold? Set off somehow . . .

      “Firefox lists all third-party modules on the page. A click on the “block this module” button prevents the module from being loaded in Firefox in the future.”

      Need a “be careful” clause: I did “block” several modules that were duplicates, but then Firefox wouldn’t load. Fortunately, one can go to the Mozilla/Firefox Profiles and find a file named “block-list” that can be deleted. Firefox is now up and running.

  8. E said on February 14, 2023 at 9:59 pm

    Does anyone know the about:config to undo the latest GPU Sandboxing?

    1. Tom Hawack said on February 15, 2023 at 10:42 am

      > Does anyone know the about:config to undo the latest GPU Sandboxing?

      According to [] :

      “Go to about:config page
      search for “security.sandbox.gpu.level” , change the value from 0 (disabled) to 1 (enabled).”

      I wouldn’t touch that but @E must have his reasons.

    2. John G. said on February 14, 2023 at 10:25 pm

      Tonight I have discovered that an online game that freezes Firefox runs now rightly after this update, so I strongly recommend to not remove the latest GPU Sandboxing. Just try and see the difference by yourself.

  9. Jody Thornton said on February 14, 2023 at 9:03 pm

    Heck, I didn’t even write anything rude, and my comment was deleted. I did cite where I thought Ghacks was headed, but I thought nicely.

    1. Martin Brinkmann said on February 14, 2023 at 9:05 pm

      Jody, your comment was not deleted or moderated. One comment is here, maybe this one was it?

      1. Jody Thornton said on February 14, 2023 at 9:18 pm

        No, you know what it was, I wrote a reply to the comment to Iron Heart, and it was aimed at you. Maybe it was deleted as a thread. I’ll live.

  10. foolishgrunt said on February 14, 2023 at 9:02 pm

    I’m going to say this as diplomatically as I can.

    It’s a joy whenever I see a good ol’ Martin article pop up in my GHacks RSS feed, amidst the recent flood of “AI this, AI that” stuff.

    1. Jody Thornton said on February 14, 2023 at 9:04 pm

      I fully agree

  11. Tom Hawack said on February 14, 2023 at 8:15 pm

    @Iron Heart, there you go again. You’re crossing the red line, that of insults. I’m blocking you with that little script you know, I’ll have a look one in a while to see if you’ve calmed down. You really seem to have a problem.

    1. Tom Hawack said on February 15, 2023 at 1:00 am

      @Iron Heart, you can say your truth without being injurious. I don’t understand how you can be sometimes so rational and some other times so excited. Don’t take this bad but I remember that you had once explained a long absence by the fact you had been ill : maybe are you taking some medicine which has side-effects?

      You even wrote yesterday something which is contradiction with the injurious comment above (which has been legitimately removed) :


      “Even if Martin Brinkmann and Ashwin still post here, I am not enough of a fanboy for it to dig out their articles from under a pile of garbage.”

      There you made a difference, rather calmly. Why such a sudden move?
      I won’t be closing any door for myself. A lot of people here really like your documented technical comments. No need to explode :=)

      1. Tom Hawack said on February 15, 2023 at 1:38 am

        @Iron Heart, I forgot to mention your reference to what appears in your view as something Martin would owe to the Ghacks’ audience. But Martin owes us nothing! This is a blog, Iron, not a hotel where we’d complain about the room service! A free place to discover, learn and exchange within our comments. Of course we can complain of what we perceive as a shift of the place over time, but not to Martin! Martin is now a site manager so to say, he’s no longer the big boss, we all know that. What to expect? Contact the owner, Martin can’t do anything about it. I’d even say he’s in a rather difficult in-between position mainly in the face of those who’ve been regulars here at the time he decided of everything.

        Things change. Rather than focusing on what we consider as a wrong move (again, not decided by Martin) let us appreciate authors we know or have learned to know and ignore if such is the case authors we dislike for valid or arguably valid reasons: Martin and Ashwin had you written yourself were those you appreciate : well, carry on with them and skip others. But neither you nor me nor anyone is entitled to yell our rights : we have no rights, not one, only the opportunity to discover day after day articles which enlighten us all on technical stuff.

    The best browser ever. Thanks

    1. Jek Porkins said on February 15, 2023 at 3:40 pm

      After Chromium. Chromium is more bester.

  13. John G. said on February 14, 2023 at 7:25 pm

    It seems to bring us some quality and important features, I hope it will be a good version! Thanks for the article! :]

  14. Yash said on February 14, 2023 at 8:10 pm

    FWIW I never had my comments deleted at all. What was written in your latest comment anyway? Another Firefox bashing!

  15. Jody Thornton said on February 14, 2023 at 7:48 pm

    Now I wish I had read your comment. Sad truth is though, the change in direction will probably improve their bottom line, albeit in the medium-short term.
