Firefox crashes whenever it would need access to my camera or microphone. So far it has only happened whn trying to access a Roll20 game with camera and microphone connectivity, and when trying to access a video appointment for Universal Credit. It never happened on Windows 10, but since updating to Windows 11 it happens every time without fail, and the crash is immediate.

FF 148.0, Intel Mac, current 15.7.4 (Sequoia)

In the middle of a browsing session I needed to consult my substantial browsing history and found it to be gone. I quit FF using the dropdown and restarted. After restarting FF the browsing history showed only that session and the TST sidebar with many tabs didn't display so I concluded FF created a new profile for startup but using my home page. I have the profile in use at the time (profile_a) and a month old backup of it. profile_a seems to have all the expected data and the bookmarks are correct. I've hacked around within Profile Groups and profiles.ini but FF refuses to use profile_a in spite of my edits, and worse is silent about it so I'm stuck and need help.

Possible related issue: is TST sensitive to the number of tabs? I'm a hoarder and find TST easier to use than bookmarks so had about 700 tabs stashed in TST.

UPDATE: efforts to fix this have revealed that it's likely the release of Profiles didn't cause this problem although I speculate there might have been an inadvertent time bomb in the release. I will open a different question searching doesn't turn up the fix. If I would delete this post if possible.

FF 148.0 was running on MacOS with my profile as a folder (e.g, trb618r9.default) under Firefox. When I looked in history it was empty so I restarted FF, none of my tabs were there, and TreeStyleTabs didn't display. Investigating I see a new folder named Profiles that has a profile in it with the trb618r9.default name but not all the data in the original trb618r9.default. I renamed the "new trb618r9.default" and moved the original trb618r9.default to Profiles and restarted FF but still am not seeing the original fxxx data which still exists.

Screenshot of finder before I renamed etc. as described above shows the two same named profiles.

How can I recover?

All of the sudden can't use Hotmail through Firefox I have tried clearing cache, making sure clocks are correct etc.

This is the error page that I get. How can I fix?

Why is the Bible.com picture blurred on my home screen but non of the other websites are? This is not very inclusive.

How to remove google search from the address bar on the right?????

I want to find my most visited websites in the address bar without any unnecessary actions!!!

All of a sudden, my default search engine changed to Google. I didn't do it and don't want it. The "settings" still show Firefox as my default, but it doesn't stop Google from hijacking my searches. I want to get rid of it.

Last time the Fire Fox updates I noticed a weird change with the browser's behavior. the browser keeps crashing just anywhere I go! I keep losing my tabs and got kicked out of the browser losing the webpages where I was! Please fix this problem and for now at the moment I would be ok if I could go back to the last old version before that happen? I appreciate your help guys!

These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.

Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.

How do I remove the icons and return to the previous performance?

It only happens on some websites (Wikipedia for one) and doesn't happen anywhere else in my system. I was unable to root out the reason for this and all solutions seem to be for when there are boxes instead. I don't see boxes, only Russian letters for some reason.

the last update disabled my group speed dial that had hundreds of saved research bookmarks. How do I go back to the previous version and restore my group speed dial bookmarks? The update should have warned that this extension would be disabled. This is a disaster!
