Mozilla plans to release a minor Firefox update later today. Firefox 91.0.2 is a non-security update that fixes two issues in the web browser, one of which affecting Firefox on Mac OS.

The new version of Firefox is not available at the time of writing. Later today, on August 24, 2021, Mozilla will make it available to all users. Select Menu > Help > About Firefox to check the currently installed version of the web browser. Firefox 91.0.2 will be distributed via the browser's automatic updating system and users may download it from the official Mozilla website.

Firefox 91.0.2

Firefox 91.0.2 is the second minor update of Firefox 91, which Mozilla released on August 10, 2021. Firefox 91 is the new base for Firefox's Extended Support Release channel. The new version introduced features such as simplified printing and HTTPS-First connections in private browsing mode.

Firefox 91.0.1 was released a week later on August 17, 2021. It fixed security issues in Firefox and addressed stability issues.

Firefox 91.0.2 fixes two issues that users may have experienced in previous versions of the web browser. The first addresses an issue on Mac OS X devices. Mac OS X users who had "increase contrast" checked in the Mac OS X settings did not have high contrast mode in Firefox enabled by default due to a bug. The new release addresses the issue in Firefox.

The second issue may have affected Firefox users who are using the password manager Lockwise. According to the bug report, Firefox Lockwise was prompting users repeatedly to enter the primary password. The initial bug report confirmed the issue on Windows, but other users confirmed it on Linux as well. It is likely that it could happen on all desktop systems that Firefox supports. The issue seems to have appeared in Firefox 90, according to the reports.

Mozilla discovered that the issue was linked to the clearing of data in Firefox. The new version of Firefox fixes the issue: Firefox no longer clears authentication data when purging trackers, to avoid repeatedly prompting for a password.

Closing Words

Firefox users who experienced the password manager issue will have it fixed later today with the release of Firefox 91.0.2. Users of the browser who don't use the password manager and don't rely on high contrast mode in Firefox are in no hurry to upgrade. The final release notes will be published here. Firefox 92, which will include the bug fixes, will be released on September 7, 2021.

    https://blog.mozilla.org/security/2021/08/10/firefox-91-introduces-enhanced-cookie-clearing/

    “Now, if you click on Settings > Privacy and Security > Cookies and Site Data > Manage Data, Firefox no longer shows individual domains that store data. Instead, Firefox lists a cookie jar for each website you have visited.”

    Do I understand correctly that from now on Firefox will no longer display third-party cookies, implicitly arguing that it’s no longer necessary because partitioning would negate the threat they represent ?

    Cookie partitioning does not remove all the privacy problems with third-party cookies. For example if I visit site.com that has a 3p request to google.com, and later I come back to site.com, Google will know that I am the same person visiting this site thanks to its 3p cookies even if they have been partitioned. And now thanks to Mozilla, we will not even be able to see the 3p cookies that Google used to track us on this site.

    Assholes.

    Anyone left using this browser? Mozilla completely ignores their user base, so I decided to stop using their browser.

      I still use FF. Works well for me.

        Still? Wow, as sad as a “I still love you” … Firefox, I love you and always will. No one, nothing is perfect but, overall (I’ve had a substantial love — I mean browser — experience) you’re the one for me!

        About FF91.0.2 :
        “The second issue may have affected Firefox users who are using the password manager Lockwise.”

        I use Bitwarden and have disabled all settings related to Firefox’s Password Manager :

        1- AUTOCONFIG :
        lockPref(“security.nocertdb”, true); // Default=false (unset) [HIDDEN PREF]

        2- GROUP POLICIES :
        “DisableMasterPasswordCreation”=dword:00000001
        “PasswordManagerEnabled”=dword:00000000

        BUT I wished to test a userChromeJS called ‘masterPasswordPlus.uc.js’ [https://raw.githubusercontent.com/xiaoxiaoflood/firefox-scripts/master/chrome/masterPasswordPlus.uc.js] and for that Firefox’s Master Password needed to be enabled and set.

        So I switched above to :

        1- AUTOCONFIG :
        lockPref(“security.nocertdb”, true); // Default=false [HIDDEN PREF]
        I’m aware of the privacy implications noted in 2017, not sure they remain pertinenet in 2021, we’re testing here anyway.

        2- GROUP POLICIES :
        “DisableMasterPasswordCreation”=dword:00000000
        “PasswordManagerEnabled”=dword:00000000 (unchanged, not needed if only Master Password : logins handled by Bitwarden)

        THEN Firefox’s Master Password was set and masterPasswordPlus.uc.js copied to my Firefox profile’s chrome sub-folder, as always for userChromeJS scripts.

        NOW :
        – with Firefox 91.0.1 I’d have after several minutes Firefox throwing a Disk space warning even though ‘browser.cache.disk.enable’ is set to false
        – with Firefox 91.0.2 the the Disk space warning issue issue has vanished.

        That’s all, folks :)

        Sorry, copying/pasting led me to a mistake :

        1- AUTOCONFIG :
        lockPref(“security.nocertdb”, true); // Default=false [HIDDEN PREF]
        I’m aware of the privacy implications noted in 2017, not sure they remain pertinenet in 2021, we’re testing here anyway.

        security.nocertdb is false when resetting to its default value, of course:

        lockPref(“security.nocertdb”, false); // Default=false [HIDDEN PREF]
        I’m aware of the privacy implications noted in 2017, not sure they remain pertinenet in 2021, we’re testing here anyway.

      I have been using FF since the Netscape days. I’m fed up with Mozilla slowly killing it, but I have not yet identified a viable browser alternative. In 2021, they all suck, FF still being the least sucky one.

      Using Librewolf (technically still FF) on desktop Linux.

      FF has its issues, but it’s the only one that can be neutered sufficiently, privacy wise.

      That, and I’m superficial. I need a cohesive desktop, meaning everything must look uniform. I can still create a custom css for Firefox to conform to my system GTK theme. Chrome and its bastard children don’t allow for that, so they look out of place and ugly as heck.

      Epiphany doesn’t count, because it lacks many features (I cannot compute without vim bindings).

      So I’m still “stuck” with Firefox.

    Firefox is still struggling on benchmark-tests like JetStream, Octane and MotionMark, compared to Chrome at least. The difference is actually quite large. I wonder why? Which tests do you use for testing browsers?

      Only test I use is check if logins are working in Firefox(thanks to password manager I know which site I have to check first), and then see whether there are performance issues in Firefox compared to Chrome. Spoiler Alert – All sites works fine and in many cases performance is better in Firefox.

    Can you write an article, even short, about Firefox profile files and description? MozillaZine’s is outdated.

    Thank you.

        Thank you. Mozilla described 21files or folders. I read it and it is good to know.

        https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_what-information-is-stored-in-my-profile

        I have over 36 files or folders.

        “What information is stored in my profile? Note: This is not a complete list. Only important information is described.”

        So, others can be deleted over and over? They are useless. Why do they exist?
