Upgraded to Ubuntu 21.10 (from 21.04 I think, didn't write it down). Now years of work, e.g., hundreds of Firefox bookmarks, passwords & logins seem to be gone.
No, I did not use Sync, nor did Ubuntu or Firefox encourage me to use Sync before the upgrade.
Those files must be on my computer, just with a deleted registry. Please, please, please help.

folder is still in the home dir, and Firefox is a snap now. Also, if you really don't want to lose them, make a backup. – mikewhatever Oct 16 '21 at 17:53tar cf moz_Oct-17-2021.tar .mozilla
