Subject: Help recovering old Firefox Sync data using my Recovery Key Hello Mozilla Support, I’m trying to recover my old Firefox Sync data, especially my bookmarks and saved passwords. I still have an Account Recovery Key that I saved on August 27, 2025. However, after signing in to my Mozilla account today, my account page shows “Account recovery key: Not set”, and syncing does not restore my old bookmarks or passwords. I may have reset or changed my Mozilla account password today without using the old Recovery Key during the process. Could you please confirm: Is there any way to use my old Recovery Key now to recover the previously encrypted Firefox Sync data? Is the old Sync data still retained on Mozilla’s servers in any recoverable form? Is there any other recovery procedure available for bookmarks, passwords, or previous Sync data? I still have access to the same Mozilla account and the original Recovery Key file. I will not send the Recovery Key itself unless there is an official secure procedure that requires it.
