Safe alternative to Sync?

Since the option to sync is missing, is there any way i can sync my browsing data?
I don’t want to lose all my favorites, passwords, etc. when i format my pc. How can i backup/restore this info?

Hello,

You can save bookmarks by exporting them to an HTML file. Passwords can be stored online through one of the password security and storage add-ons available for Firefox.

Regards.
