Hi It appears from your question that you are using Firefox Sync as a backup service. While it may be handy in some cases (such as [[Back up and transfer your Firefox data to a new device | transferring your data to a new device]]), we do not recommend relying on Sync for backup purposes. If you have a copy of your Firefox profile for desktop Firefox, you should be able to recover your bookmarks and other data. To restore bookmarks, see [[Restore bookmarks from backup or move them to another computer | this article]]. For instructions on recovering all of your data, see [[Restore bookmarks, passwords, and data from an old Firefox profile]]. If you have your data in Firefox on a mobile device, please follow [[How do I set up Sync on my computer?#w_connect-additional-devices-to-sync | these instructions]] to connect it to Sync and copy the data. Be aware! Resetting your Mozilla account password without a recovery key will erase your data from Mozilla servers. Make sure to [[Reset your Mozilla account password with Recovery Keys#w_generate-and-store-your-account-recovery-key | generate a recovery key]] in advance and safely store it. Hope this will help you resolve your issue!
