Dear Firefox,

I have FINALLY given up on your sync feature as it keeps adding deleted bookmarks and folders. It is so bad that all the duplication of bookmarks and folders are so random that can mount to thousands and thousands or copies.

I have UN-SYNC all my devices as this cannot go on as I have followed your instructions to the T.

Just that you know.

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).

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).

Dear Firefox,

I have followed your instruction to a T on my devices and I have treid a few times.

Unfortunately, it did not work.

I guess I will just have to live with unsync the browser on all my devices.
