Long time Firefox user. Had automatic update to version 121.0 on 12/19. Shut down that night. Next morning (12/20) Firefox opened as if it was a totally new installation - no bookmarks, extensions, etc. Downloaded 121.0 64 bit version; uninstalled Firefox; reinstalled it with downloaded version - same issue. Replaced profile with backup copy from 12/17. Firefox started properly with all bookmarks, extensions and other settings.
Shut down on 12/20. When computer was started this morning (12/21) and Firefox opened - same issue - presented with brand new never before opened Firefox. Shut down Firefox, copied over 12/17 profile, restarted and all bookmarks, etc. were there. Restarted Firefox using about:restartrequired and everything was still as expected.
Windows 10 is up-to-date. No updates found for extensions.
Thoughts on what might be corrupting the profile or what steps I can take? I have 25 enabled extensions. Since a restart didn't revert me to the brand new never opened presentation, activating them one at a time doesn't seem to be a worthwhile approach.
