Lost bookmarks when synced

Terry

How can I retrieve lost bookmarks? Syncing between two Firefox browsers replaced my newer bookmarks with the bookmarks of my less-often used browser. I expected the newer bookmarks to appear on the other browser. But instead the more-often used browser now has the same bookmarks as the less-oft used one.

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

This can be caused by a problem with the places.sqlite and favicons.sqlite databases in the Firefox profile folder.

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

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

If "Verify Integrity" cannot repair places.sqlite, rename/remove all places.sqlite and favicons.sqlite files in the Firefox profile folder. Firefox will rebuild places.sqlite and restore the bookmarks from a 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
