New Firefox user here. I did an update and afterward, my entire Firefox reset?? All profiles deleted. I couldn't find my old files to restore. My old tabs are in "Tabs from other devices", though.
This is so frustrating, I don't have my Firefox browsing history saved. I managed to find the bookmarks and extensions but everything else is gone now. I have to re-login for everything. This is such an infuriating bug and I'm considering switching back to Chrome or trying a browser like Opera. I never even ONCE had this issue when I used Chrome for YEARS.
