My computer crashed and after restarting I have lost my account data including profiles, history, bookmarks, extensions, open tabs, etc. I have tried the basic methods suggested online like looking for hidden profiles, finding a folder for old Firefox data on the desktop, restoring from apparent backups that are meant to be there, etc. The account should have been logged in all this time and had sync on, which is not working... but should there be some sort of sync history I can restore from? Or a local backup from somewhat recently? Thank you
