Firefox 社群討論區

I have a warning underneath my bookmark ribbon that says, "The security sandbox is disabled. Your configuration is unsupported and less secure." What is the security sandbox and what configuration is needed so that it supports the security sandbox. What happens if this security sandbox is disabled while I'm running Firefox?

I'm running Firefox v146.0.1

A leak was detected on my account then Mozilla locked it. Every passwords were changed as I still got an "Email just returned" error upon trying to sign in, and now I end up with an "Unexpected error".

And to make sure that this has nothing to do with the plugins I have on my pc installation, I tried signing in on mobile phone as well. Same issue.

I have a new laptop and am using Firefox as my browser. But when I'm on Facebook, go to chats it says that video chat isn't supported by this browser. Does Firefox not allow this? I've tried going to permissions to allow Facebook to access my camera and microphone, but unable to do so. How do I use the video chat feature in Facebook chats?

Hello, I have tried everything...filters, added contact, blocked senders but I'm still not receiving any email from Firefox. I need my verification numbers to continue to sign into my account. thanks in advance for helping, Scott

Suddenly Firefox has begun to play bell tones for clicks with my mouse.

I am unable to disable this new behavior. It is ONLY happening with Firefox. No other browsers behave in this manner.

My PC sounds are shut off.

I never want bell tones ever at any time. Please help me discontinue this behavior as soon as possible. As someone who works with professional audio recording this is especially undesirable and disturbing.

Please. Somebody. Stop the madness.

Thanks!!

SUBJECT: Profile missing after update to 146.0.1 

After the last Firefox update (146.0.1), I can no longer access my profile that included bookmarks, history and passwords.  

After the update was done on 12/19/25, I was given the option to choose between my original profile and a newly created one. The next day when I opened Firefox, there was only one profile shown and my original profile was gone. I have read numerous fixes for this problem but nothing seems to work.

I have done the following to try to locate my missing profile to no avail. 1. I went to the Profile Manager but the only profile listed was the newly created one. 2. I didn't do a refresh so there was no "Old Firefox Data" folder to copy the data from. 3. Used about:Profiles, Again only the newly created profile was listed 4. I used ~Library/Application Support/Firefox/Profiles. Still no luck. 

Could my profile have been moved to another place or could it be hidden? Any help would be greatly appreciated!

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?

so i was using my pc (and firefox) normally, when i then turned off the machine as usual.

when i turned my pc on again and opened firefox, everything was gone, i wasn't signed in and all my bookmarks and several home url's were not there, you don't need me to tell you that's not normal.

of course, i followed the most logical course of actions, i signed into my firefox account (from which i am sending this ticket), and expected all my data to magically sync, which it didn't, so i then tried to sync in manually, looking for any backup file on my pc (i couldn't find any, though i can't say i know what one looks like so...)

hopefully this can be fixed because i had auto-sync on and it would be a bummer to lose everything and slowly rebuild my browser ui from the ground up

thanks in advance, GR
