I upgraded my Dell PC to Windows 11 yesterday via Windows Update, since support for Windows 10 is ending. Now Firefox crashes often when I close the browser. Everything works fine while I'm using Firefox, it's only when I close the browser that sometime later I will get a crash message on my desktop. I have tried uninstalling Firefox and reinstalling it, and the problem persists. From what I can tell, there's some process which is ongoing after the browser is closed, which isn't terminating properly and that's why it's crashing. I have submitted several crash reports, but don't know how to post them here.[bp-2e2d8f06-4c87-43a6-8b32-b0f5a0251006]

Just as an update, I found something somewhere which says I'm using Firefox on Windows 10, which doesn't make sense. I do know the Win 11 upgrade migrated all my data from Win 10, but why does some stuff say I'm still using Firefox for Win 10?
