Am I correct in thinking that Firefox sync ensures that an entry in say the Bookmarks folder is copied to all machines on my account. This implies that if I delete a bookmark on Machine A synch will find it on Machine B and replace it on Machine A. How then am I to delete unwanted entries other than by closing synch and deleting separately on each machine? Is there a facility for making one machine the master so that the remaining machines duplicate the master?

Any changes on one member of the sync is sent to all members of the sync. Edit/Remove/Add something on one is shared with everyone.

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 -> 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 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

You lose the history when a new places.sqlite is created.
