Hello Mightymad,

Thank you for contacting Mozilla Support. Sorry, about your loss of data.

Sync isn't intended for the purpose of being a "backup" service while the user re-installs their operation system. It was made to synchronize data between Firefox installations on multiple devices, where not every device is devoid of their Firefox installation and data at the same time.

Unfortunately, if you've overwritten the Sync data your previous version is lost.

I wish we had better news for you, but hopefully this gives you a better idea how Sync works, so you're better prepared next time you go to reinstall.

Did you previously uninstall Firefox and have removed your personal data (i.e. the Firefox profile folder)?
