HI Swimnbud, After a clean reinstall of the operating system or a clean reinstall of Firefox? There might be a difference here because if you uninstall Firefox, sometimes the profile files are still there:

If you reinstalled the Computer, only the actively syncing profiles will sync to the newly installed system.

If data was lost, I am sorry that this happened. However Firefox sync is not a reliable back up for a Firefox profile. It will sync actively synced profiles.
