Bookmarks are synchronized from void over again

more options

Hello, I have a problem, where many bookmarks from my old device are synchronized to my current Firefox browsers (on PCs) even when old device is removed months ago. What worse, when sync is performed, it duplicates tabs, now in "Bookmarks menu" I have albost 2000 bookmarks what are duplicates od ~20/30 ofer month. If Firefox do sync now on 2nd PC, I will get again 2000 and plus something bookmarks. Deleting it gives nothing. It comes back again and again. Normal Bookmarks tabalso gets old tabs and duplicates.

Chosen solution

As a Firefox support volunteer I don't have the ability to modify something in others accounts and as I know no one can. By the way, at this thread the similar problem was discussed: https://support.mozilla.org/en-US/questions/1155190 And the solution was to wait 7 days after changing the password. Please bump this thread to let us know if it works in your case.

Did you try to disable sync on your old device? https://support.mozilla.org/en-US/kb/disable-firefox-sync

I cannot do this because I do not have this device anymore and the device is removed from my devices list.

So, the same happens. Is it possible to contact support to delete all my bookmarks assigned to my account?

If you use Sync, best is to disconnect Sync temporarily during troubleshooting.

This could be a problem with the places.sqlite and favicons.sqlite files in the Firefox profile folder.

  • use the "Places Database" -> "Verify Integrity" button on the "Help -> More Troubleshooting Information" (about:support) page

If errors are reported with "Verify Integrity", close and restart Firefox or reboot and retry.

If "Verify Integrity" cannot repair places.sqlite, rename/remove all places.sqlite and favicons.sqlite files in the Firefox profile folder with Firefox closed. Firefox will rebuild places.sqlite and restore the bookmarks from the most recent JSON backup in the bookmarkbackups folder.

  • keep a backup copy of places.sqlite in case a new places.sqlite database has to be created
  • you lose the history when a new places.sqlite is created

You may have to restore an older bookmarks backup in the bookmarkbackups folder via the Bookmarks Manager (Library).

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

@Alex R - looks like password change and constant deletion of additional bookmarks helped :) Thank you
