If you go to the about:sync-log page in Firefox, do you see any recent error logs listed there?

Firefox Sync is NOT A DATA BACKUP SERVICE. It wasn't designed to be one and it doesn't function as one. There isn't always a complete or permanent copy of your data stored on the Firefox Sync servers.

Additionally, certain account actions (like resetting your password) erase your data from the Firefox Sync service.
