I upgraded from 21.04 to 21.10. Other (non-sudo) users of the computer reported that their Firefox profiles were lost.
I uninstalled the snap firefox, and installed deb firefox via apt. Their profiles "came back". I guess the snap firefox looks for profiles in a different location, and the profiles aren't transferred from the old deb-firefox location to the snap-firefox-expected location. It looks as though this transition to snap firefox has been done badly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947257 Title: Partial profile loss on upgrade from 21.04 to 21.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1947257/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
