Firefox keeps crashing. I tried refresh and am afraid to totally uninstall for fear of losing my tabs and data. Why is this crashing all of a sudden. Also will not play Youtube videos. I have cleared cache and history.

Without warning or input from me, Firefox shuts down and upon me reopening firefox, my Outlook Hotmail E-mail account doesn't recognize my set password? I have to keep resetting my password each time???

Anybody knows if this is a Microsoft issue, or is it Firefox?

tried few below steps Remove all Extensions, Reset Browser again if same issue remove the user profile and login with the new profile if same issue try un-installing and re-installing browser with the different account did a clean re installation by removing local files from the help of forced uninstaller reinstalled it but the issue still persist also tested by disabling antivirus although the computer worked with mcafee earlier please provide a solution to this computer is running on win 11 with the latest 25H2 update

I ran a Windows 11 Update and after I opened Firefox, it shows all the tabs that were there but each tab indicates that it's 'Crashed'. The 'Tab Crash Reporter' doesn't restore a single tab nor does it react to 'Restore all Tabs'. It looks like Firefox is NOT connecting to the web.

I'm entering this using the Edge browser.

Thanks in advance, Bob

On a daily, my tabs crash and won't restore. The only way to fix is to close Firefox and reopen. When I reopen, I'm prompted to create a new profile. This happens daily on the ESR version. There's no crash reports or anything. It's become very unstable and a pain to deal with. I've reinstalled Firefox from scratch, removed all remnants of all profiles, and it still happens.
