Did you save the Recovery Sync key you were given when you synced Firefox? Or do you have an actual backup of your data? Sync isn't a backup service and shouldn't be used as one.

Firefox automatically creates backups of your bookmarks, which can be helpful if your bookmarks are lost or missing. To recover them, follow the instructions below.

1. Use one of these methods to open the Bookmarks Library window:
   • Click the Firefox button to open the menu and click on Bookmarks.
   • Click the Bookmarks menu and click on Show All Bookmarks.
2. At the top of the Library window, click the "Import and Backup" menu and select Restore.
3. Click the date of the bookmark backup you want to recover.
4. In the new window that appears, click OK.
5. Your bookmarks from the selected date should now be restored.

For more information, see the Restore bookmarks from backup or move them to another computer article. For other solutions, see the Recover lost or missing Bookmarks article.

Did this fix your problems? Please report back soon.

You should just be able to sign into sync on the new browser. This should work if the previous browser was connected to the sync feature.

There was only one date available and that was after the factory reset

Sorry, but like Tylerdowner said above:

"Sync isn't a backup service and shouldn't be used as one. "

If you have no previous data backed up and do not have the sync key, there is no way to recover your bookmarks.

We apologize for any inconvenience.
