ff took a dump on ALL my tabs, info, etc.

only one email kinda working now - ''[email 1 removed]''@wolfgangforge.com (have 3 accounts total). i cannot even be sure you are getting my emails or that i am receiving any replies. when i close down ff and re-start, the email tab is gone and i must type in "https://sm1.toast.net/interface/root#/email" and login to get it running again. my most important email, ''[email 2 removed]''@wolfgangforge.com is not. this folder has my business tabs (using the Simple Tabs add-on in ms windows 11) - about 700 tabs and about 30 groups. '''''losing all this info would be a major disaster!''''' it is like FF is installing for the first time and cannot find the Profiles folder. i've attached a screenshot to show the folder where the Profiles are presently kept. '''''***-- i need to get back my ff as it was last friday.''''' i looked at the session-restore, but it appears that only goes back to the immediately previous session and since that one was fouled-up also, i can't see how that would help. wolfgang 503-475-3563
