Google Search CAPTCHA persists unless you sign in to your Google account. This only happens in your browser, from versions 140 to 149. Other browsers don't have this problem. Changing the user agent used to help. Now, nothing works.

Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

I'm using Firefox esr, the latest version 149.0.2. Since this update, I can no longer load the videos on NPR.org's home page. Something pops up, but then the wheel/circle thingie just goes round and round, and never loads the video.

My ad blocker was already off for this site. I've tried restarting Firefox in Troubleshooting mode, and changing the various security settings mentioned in this article: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings, such as adding it to the "Allow popups" exceptions (never necessary before) and other settings. I've reloaded the page multiple times, restarted Firefox, etc.

Can anyone suggest anything else to try?

My Teams will not open on my pc laptop. It's tiny icon only flashes, I tried to sign in to microsoft and to the old skype but am told my passwords were compromised in 2024 and am sent to archive.org to change. I do not understand this archive site or what I am to do. Are their any interpreters for those who can't find direction? Thanks so much

I tried checking Instagram today but it got stuck in the loading screen and i cant check my friends' DMS, when i try Microsoft edge, it works what's goin on and how can i fix that? i tried clearing cache and it didnt work

First off - love Mozilla's work, thank you all for your efforts!

The problem: I f'd up with the Profiles option. I wanted to set up a Work profile on a new windows laptop associated with a new work email (msta....), and then separately have my personal profile connected to my gmail (mstn...).

Well somehow I managed to make my Work (default) profile connected to my overall Firefox + Google personal profile, and have spent a month in my ignorance saving away settings and bookmarks on this machine. Is there anyway that I can disconnect my Gmail account from the profile Work, and connect it to the secondary profile on the same machine titled 'Mel'? Or will I need to export the last month of bookmarks, implode my Mozilla install on this machine, and start over with new profiles and better practices?

Help, multipass!

Thanks, Mel

I face an issue with the browser crashing when in google meeting (meet.google.com). The problem persist in a new profile created with 'firefox.exe -P' and also in the troubleshooting mode. The crash is triggered when I am in the google meeting (with allowed microphone) and I manipulate with windows of the browser - across multiple monitors (switching tabs, moving tabs between windows, closing firefox windows, opening them, "dropping" the tabs onto another applications - chrome, spotify - which opens a new firefox window). Sometime the crash happened once I closed the google meeting tab. Unfortunately it happens "randomly" and I was not able to come with a specific series of steps to reproduce the crash. But it happens always when I am in the meeting and play with the windows for a while.

The crash: Firefox freezes for a few seconds (~3s) and then closes itself - all windows. %appdata%\Mozilla\Firefox\Crash Reports\pending contains a new .dmp file, but it has 0 bytes and no .extra file is created, hence it cannot be submitted via about:crashes. The crash reporter is not opened when firefox crashes. The attached troubleshooting information are from the new clear profile where the crash happens as well.

I Loged In To My Firefox Account Today Done My Work and Close the Browser and Shutdown The Computer. On next Day When Again I On My Computer And Open Firefox The Firefox Account Gets Logged Out. I Am Facing This Issue From Long Time. I Want It Shoud Be Logged In and Only Loged Out When I Do. Plese Help Me Out.

I just lost my bookmarks again, it happened a month or so ago as well. Appears to have been due to updates.

I have already followed the recommended ideas of navigating to restore, but there is no date given to restore to.

Just "choose a file comes" up, and that appears to lead nowhere.

I also went about:profiles , and all that was there was the current "cannot be deleted " profile and the option to make a new one, I tried that, it did not restore bookmarks. I need some of tose bookmarks quite badly this time

What more can I do ?

pourquoi "acheter" AdBlock puisqu'elle est proposée gratuitement? a ma connaissance c'est la seule extension Firefox à me proposer une contribution payante. Je refuse of course!

I don't really want to disable storage or ALL cookies. But I DO want to COMPLETELY sanitize on shutdown. While this policy is effective AND network.cookie.noPersistentStorage in config has been set True, NEITHER stops Persistent Storage nor cleans it. ONLY manual cleaning (deletion) of persistent storage is available in Settings: Privacy & Security: Manage browsing data. There is no other option available that I can find. One solution suggested a setting that both disallowed cross-site cookies AND isolate other cross-site data but there is no setting like that. There are TWO separate settings for that. Besides, that is not what is wanted.

How can I either completely disable persistent storage - or, more preferred is to completely clear persistent storage upon quitting?!

I have everything else cleared on quitting but persistent storage is indeed persistent. If I have to, I will disable it completely (not preferred) but do NOT want to disable ALL storage use.

Why doesn't network.cookie.noPersistentStorage not work? Or, if it does, what does it actually do?

I would like a policies.json entry for this as I already employ the file in /etc/firefox/policies as described. This is the preferred method for multiple users.

I am using Ubuntu and Firefox Snap for Ubuntu 149.0.2 (64-bit). Let me know if other information is needed. Thank you.

Previously, had no problem loading YouTube videos in multiple tabs, switching between them and them playing their videos with no freezing , pausing or buffering. Since the last upgrade loading a single YouTube video causes it to freeze and continually buffer. And Firefox is spawning multile copies of itself in task manager. (One instance had 15 copies.)

The camera just won't work on google meet. It works on zoom and teams just fine. The camera preview before joining a meeting on google meet also works just fine. Sometimes it works on private mode but not always. It works perfectly on other browsers. I have turned off extensions, removed protections and restrictions, created a whole other user account on my laptop and installed firefox on it just to test it out (without signing in/syncing settings) and it still won't work. It doesn't matter whether I'm signed into a google account or not or if it's my meeting or someone else is the host. On private mode it only works if I'm signed out but again not always. Not sure what's up

I'd like to know how to hide the previews for vertical tabs in Firefox. I've already unchecked the "Show preview image when hovering over tabs" option in the settings. Is it impossible to hide them?

Hey there Mozilla team, Love the new free built-in VPN for the browser and Kit. :D But I have problems with enabling the VPN. I am on Linux Kubuntu and the VPN cannot start. Funnily enough when i turn on Mozilla VPN on device level the Browser VPN does manage the enable itself.

Also I have a question about the Mozilla VPN browser extension. Is support for Linux still being worked on? And could we see the support being implemented soon?

Have a wonderful Day

I had a problem where FF 140.0 would not update, and in trying to get FF yo update, I used a re-install tool to which I was pointed in my problem report. This caused FF to wipe out my configuration, and I lost all my windows and tabs. I have gone to

    \Appdata\Roaming\Mozilla\Firefox\Proifiles\abnfpged.default

cleared all of the data therein, and restored that directory from a backup I made last Monday. But I cannot get FF to use that directory. "about:profiles" shows only two profiles, but the Profiles directory has five profiles:

03/10/2026 09:39 AM <DIR> qf00ka5x.default 03/10/2026 09:39 AM <DIR> v842ceue.default-release 04/11/2026 09:16 PM <DIR> .. 04/11/2026 09:16 PM <DIR> . 04/12/2026 03:08 PM <DIR> abnfpged.default 04/12/2026 06:29 PM <DIR> jdfj91sd.default-release-1775960183850 04/12/2026 06:48 PM <DIR> f1jq4mlq.default

Only the profiles beginning with "j" and "f1" are seen in the "about:profiles" screenshot I have attached. And I have attached a screenshot of my profiles.ini file. Also, in the abnfpged.default directory I restored, where is the list of all of my open windows and tabs? FF used to keep that in a sessionstore.jsonlz4 file, but that file is only written when FF closes. I tried to save a copy when I was having problems, but I stored the copy in the same directory, which FF changed during the re-install process. Here is my profiles,.ini file:

[Install308046B0AF4A39CB] Default=Profiles/jdfj91sd.default-release-1775960183850 Locked=1

[Profile1] Name=default IsRelative=1 Path=Profiles/f1jq4mlq.default

I have not worked with the ;profiles.ini file in many years, as my FF configuration has not had problems. Thanks.
