Firefox Bookmarks duplicating.

For some reason, sometimes in minutes and other times hours, my bookmarks keep duplicating. Often a duplicate shows up under the original bookmark as well as A-E alphabetically duplicating at the natural end of the bookmarks, i.e. after the last (Z) alphabetical bookmark. I deleate the duplicates and they come back within minutes. I logged out of sync but still have duplicates forming. How do I stop this?

Are you using Sync to Sync the bookmarks as that could be a possible cause?

If you use Sync then 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).
