Firefox Community Forum

Some users are abandoning Firefox because of the difficulty of protecting against Firefox fingerprinting. Therefore, I strongly recommend adding an option in the settings that allows the digital fingerprints to be made random, or at least, if it is difficult, to make the fingerprints indistinguishable. This will help improve Firefox’s reputation and the privacy of its users. Love you all 3:

If you do provide one, is it in real time can it see my screen at the same time as I'm using it? Does it use a sandbox or a slide deck? Does it use voice? Can it develop apps does it use sub agents? Thank you

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

First of all I've noticed that even logging in to the account management page doesn't work with my vpn on. So of course sync itself doesn't either. It works perfectly fine with it off though. Is there an IP address that I can add to split tunneling to allow only the sync/FF account manager through my vpn? Or another way I'm not aware of? I'd rather not have to allow the whole browser through my vpn if possible.

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

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