</p><p>If you haven't already, please do a normal exit/quit of Firefox and a normal shutdown/restart of your system to free up file locks and complete any deferred updates.
</p><p>If problem continue, please see the following article: <a href="/en-US/kb/fix-bookmarks-and-history-will-not-be-functional" rel="nofollow">Fix "The bookmarks and history system will not be functional" error message</a>.
