thanks, does it work when you delete the places.sqlite file in the current profile, restart firefox once and instead load a bockmarks-backup from the old firefox folder on the desktop? https://support.mozilla.org/en-US/kb/restore-bookmarks-from-backup-or-move-them#w_restoring-from-backups

I delated all places.sqlite in the current profile, but nothing happens when i try to load bookmarks from the Old mozilla folder.they just dont show up.But now i can add new bookmarks

Actually after I tried a few bookmarks from the OLD mozilla folder, I managed to get the bookmarks back.So everything is ok now.Thank you for your help
