I have set Firefox to complete the address bar with elements from the history only ( other options are: nothing, bookmarks, and a history+bookmarks).
However, Firefox still continues to complete the address bar with elements that are no longer in my history. A search in the history returns 0 result for the incriminated string. How can I solve this without loosing my entire history? I have already tried shift+delete on the elements I would like to delete, without success.
How can I find the source of a certain completion ? (like an SQL request in the sqlite3 files used to store history)
I'm using Firefox 16.0.2 on OS X 10.8.2.
