Firefox was running slow and it recommended to perform a reset. After the reset all of my bookmarks were lost and not restored. I found the backups of the bookmarks and each of the stored backups gives the same error "unable to process file". I tried this on all of the files. How can I get my bookmarks restored?

This can be caused by a corrupted places.sqlite database.

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

This issue 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
