Updated • Jul 26, 2022

Firefox 103 and Firefox 102.1 ESR will be released later today. The new Firefox 103 Stable release fixes security issues, improves performance and the browser's picture-in-picture mode, adds new toolbar keyboard access and more.

Mozilla publishes updates for all Firefox development channels as well. Firefox Beta and Developer editions are updated to version 104, Firefox Nightly reaches version 105, and Firefox for Android will be upgraded to version 103, as it follows the stable version.

Executive Summary

  • New toolbar access via keyboard, which could break Tab-key workflows for Firefox users who use the address bar and search bar.
  • Total Cookie Protection is enabled by default.
  • Firefox 103 fixes security issues. These have not been posted yet.

Firefox 103 download and update

Firefox 103 and all other versions of the browser released today, will be distributed via the browser's automatic updating feature. Updates may not yet be available, if you are reading this on the day of release.

Direct downloads are also available, follow the links below to Mozilla's download website, to download the new version of the browser.

Firefox 103.0 new features and improvements

Toolbar access using the keyboard

Mozilla extended keyboard access to the toolbar in Firefox 103. Pressing Tab or Shift-Tab moves between different groups in Firefox's toolbars and even on the webpage now. Once a group has been reached, users may use the left and right arrow keys on the keyboard to navigate the group. Pressing Space or Enter will activate the toolbar button.

Here are all available shortcuts in an overview:

  • Tab -- moves to the group to the right of the current one.
  • Shift-Tab -- moves to the group to the left of the current one.
  • Right-Arrow-key -- moves to the next element of the active group.
  • Left-Arrow-key -- moves to the previous element of the active group.
  • Space -- Activates the active icon.
  • Enter -- Activates the active icon.
  • F6 -- return to the web page.
  • Ctrl-L -- focus the address bar of the browser.
  • Shift-F10 -- access context menus of buttons.

Restore the old behavior

Firefox users who prefer the old behavior, the switching between the address bar and the Search bar, may restore it in the following way:

  1. Load about:config in the Firefox address bar.
  2. Select "Accept the Risk and Continue" if the warning page is displayed.
  3. Search for the preference browser.toolbars.keyboard_navigation.
  4. Activate the toggle button to set the preference to FALSE.

Other changes

  • Improved performance on high-refresh rate monitors with 120Hz or more.
  • Fixed an issue that could slow down Firefox startup.
  • Improved responsiveness on macOS during high CPU usage.
  • The "Make text bigger" accessibility setting on Windows applies to all user interface and content pages, instead of just system font sizes.
  • Firefox will be pinned to the Windows 10 or 11 taskbar during installation.
  • Required fields are now highlighted in PDF documents.
  • Picture-in-Picture subtitles support changing font sizes now. Also, support added for subtitles at Funimation, Dailymotion, Tubi, Hotstar, and SonyLIV
  • Total Cookie Protection is enabled by default (finally).
  • When copying text from forms, non-breaking spaces are now preserved.
  • Addressed WebGL performance issues on Linux when using NVIDIA binary drivers via DMA-Buf.


  • Native Error types can now be serialized using the structured clone algorithm.
  • ReadableStream, WritableStream, TransformStream are now Transferable objects.
  • caches, CacheStorage, and Cache now require a secure context; the properties/interfaces are not defined if used in an insecure context.

Enterprise changes

  • Configuration option to allow SHA-1 signatures has been removed.

Known Issues

    I was satisfied with Firefox before the “rapid release” versions came along, and every time I updated everything broke. Having to constantly mess with a browser every time it updates to make your extensions, preferences, add-ons (like Flash) work is inexcusable.
    How about going back to the once every two years major release versions, and dropping this once every six weeks nonsense. Mozilla can’t do it right, and doesn’t need to “keep up with” Chrome, nor have version numbers like Chrome (which at least doesn’t break ANYthing with incremental updates, nor major changes at all.
    Latest version 103 seems to work OK, but we’ll see how long that lasts. I’m certainly not making it my default browser.

    I am just p***ed off with getting update notices on my PC every few days from this product. Why can’t they reduce the update frequency to once per month. I was satisfied with this browser when it was in the 50s and couldn’t care less about all these kooolle new features.

    “Firefox users who prefer the old behavior, the switching between the address bar and the Search bar, may restore it in the following way:..” – more a need rather than a preference to resort to disabling this “feature” as my Firefox start times were noticeably slower than previous versions!?

    On systems where Windows dpi scaling is not 100% the new Firefox 103 shows everything HUGE. Chrome – and Edge also I think – already have the compatibility with these Windows settings, but they display all elements with reasonable magnifying factor. Thas does’t occur with this new Firefox, that makes it unusable on some cases.

    Fortunately you can adjust everything ( but it’s an annoying issue, especially for non-techsavvy users.

    Firefox should dedicate at least the next two versions to UX improvements, its way behind Chrome in this regard, and the fact that you cannot set custom keyboard shortcuts is embarrassing at this point. Maybe they should hire some devs from the Opera team.

  6. Saad said on July 27, 2022 at 2:25 pm

    The performance of Firefox is very bad, especially on pages containing multimedia, which all stutter in playback. i benchmarked Firefox and Chrome in my PC. Chrome score became 40 , Firefox score became just 9 !!
    Although I get annoyed with Firefox, I still prefer to use it.

    “Floorp”: Open source Firefox-based web browser developed by a community of Japanese students (high school students)
    From the above information and others,
    I was surprised to see a glimpse of how an active duty “high school student” had “Worked on the development of OS (Linux) distribution and browser, and released it as a product in a very short period of time”.

    I actually put “Floorp” to the test.
    It is a “level of completion” that runs very smoothly, has excellent performance, and uses very little RAM.
    The platform Firefox (ESR) is Since it is essentially for “corporate use”, can add enterprise policies to the preferences (about:config), which can be difficult to set up properly (and esoteric to the average end user), but I feel that “Floorp” is a great finished (already surpassing Pale Moon and Waterfox).
    With Floorp, I realized that “an amazing new generation is growing.”

      That is such a great off-topic! Thank you very much for bringing that up. Unfortunately, both review sites you linked are in japanese. Github page does not reveal much of browser targets, ideas, what is improved and what is dropped from vanilla FF. Although you posted some specs, would you elaborate a little bit on this browser?

      Btw, when I tried to post this comment using Floorp, an error page came up saying that I’m commenting too fast, one shall slow down.

        Floorp Features & Functions
        Floorp is a forked Firefox, but what it can do and what it can function are different.
        Since Floorp is based on Firefox, Firefox Sync is available. This allows for easy migration from Firefox, forked Firefox, etc. Migration from Microsoft Edge, Google Chrome, and Internet Explorer is only a few clicks away.
        Floorp has multi-level tabs, Tree Style vertical tab, and Tab positioning function built in by default, and there is no need to load unsupported scripts. Just turn it on/off via the Settings!×960.png
        Floorp does not force a design on the user. You can display only what you need, in any design you want, in any arrangement you want. It is the one and only browser that allows you to change the design by default (The developer was a contributor to the development of Vivaldi and Brave.)×917.png
        Floorp respects the user’s decision, but there are times when the choices are not enough. Floorp is a browser that allows you to edit CSS from within the browser and apply CSS without requiring a restart.
        It is possible and easier to making your own choices, making it easy to build your own unique browser.×960.png
        Floorp comes preconfigured with uBlock Origin, Safe Browsing, and encrypted Firefox synchronization.
        No telemetry and no information collection. There is no concealment and Floorp does not collect any user data. The only information collected is browser data and access information for the API used to measure the number of Floorp users, which does not include personal information.
        What you did with your browser, web activity, is not collected by any third party or browser developer.
        Floorp is an open source browser provided under the Mozilla Public License 2.0. Also, the Floorp project, the developer of Floorp, respects its origin, Mozilla. Search engine revenue goes to Mozilla. Floorp is backed by user donations, and all donations are used to be better the web and are returned to users.

        Floorp has “Frea Search” built into the Search Engine and can be selected as an alternative search engine.
        What is Frea Search?
        Frea Search is a modified self-hosted search engine called SearXNG. SearXNG is a meta search engine that aggregates and displays results from multiple search engines. It is open source and extensible.
        Frea Search gets results from multiple search engines such as Google, Bing, Duckduckgo and Brave search. However, it does not display the results as it is, but uses its own blacklist to exclude useless sites from the results. Over 7,000 websites are registered on this blacklist and will continue to be expanded in the future.

        Advantages of Frea Search
        Free from affiliate articles, programming school articles, Stack Overflow machine translation reprint sites, overseas ROM-burning copy-and-paste articles, scam sites, etc.
        We protect your privacy. We don’t do any tracking. Access logs are kept for security reasons, but we guarantee that we will never release them to anyone other than the server administrator unless legally ordered to do so.
        It is also a fact that our accuracy is currently not as good as that of Google and other search engines. We plan to improve the accuracy in the future through cooperation with upstream companies and development of plug-ins, so please stay tuned.

        My regular browser has been Floorp since July 20, 2022. The current version “10.2.0” was applied by automatic update.
        I also use Floorp for posting to ghacks.
        Regarding “an error page came up saying that I’m commenting too fast, one shall slow down.”, In my experience, it was because JavaScript was blocked by the “uBlock Origin” implemented in the browser. If it enabled, the problem has been resolved.

    The major upgrade version of Firefox ESR (and Thunderbird) is “102”,
    but for existing users of 91.x, the latest version will be automatically updated with 91.12.0 ESR (rather than Firefox 102.1 ESR).

    1. owl said on July 27, 2022 at 1:41 am

      This is because the “compatibility” check associated with a major upgrade from 91.x ESR to 102.x ESR is required, and automatic updates are intentionally blocked.
      Optional manual updates are possible, but are not recommended due to unexpected glitches.
      Please wait for the automatic update without performing the manual update.

      Thanks for spotting that. It is August 23rd according to the release schedule.

      FF 104 will obviously we available in August, for sure. Should be August 22nd (+4 weeks).

      Houston : we have updated to 1-O-3.
      Being a mouse aficionado I’ve already disabled the new extended keyboard access to the toolbar.

    > “Improved responsiveness on macOS during high CPU usage.””

    I’m curious about this. Firefox uses a lot of energy on M1. I hope this update fixes the battery drain issues.
