Thank you for your suggestion Happy112.

My pleasure - I only hope it works ......

I did what they suggested me to do, but doesn't work. I'm desperate because I have more than 200 bookmarks in my original account. Those were for my doctorate thesis research project. My computer broke down, so I need to restore my account ASAP. I already did with everything else in my pc.

I called for an administrator. Please wait.

Hey,

I am sorry, but you need to have access to at least one email account that the sync account was created with. If you still have access to the account you can add a new email account there. However, please know that sync is not a back up. The local profile will have the bookmarks if no other edits were made to that computer that originally synced them.

If you are looking for them try these troubleshooting steps: 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:
   • Firefox 29 and above: Click the Bookmarks button and select Show All Bookmarks.
   • Previous Firefox versions: Click the Firefox button and click on Bookmarks. (If you don't have a Firefox button, click the Bookmarks button or Bookmarks menu item and select Show All Bookmarks.)
2. At the top of the Library window, click on Import and Backup 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.

Thank you.

Can't you create a new Sync account with the correct email address?

You can disconnect from Sync by clicking the e-mail address in the "3-bar" Firefox menu button drop-down list or go to "Options/Preferences > Firefox account" if you are currently connected.

If that isn't working then try these steps:

Delete the signedInUser.json file in the Firefox profile folder and delete the Weave folder (Sync was formerly named Weave). Remove an existing chrome://FirefoxAccounts entry in the Firefox Password Manager. If that isn't enough then delete the prefs.js files to reset all prefs and maybe also delete the compatibility.ini file to reinitialize the profile.

You can log in to the Sync account via this page.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
