Follow up from Bug 603817. In that bug I was told not to use the events DOMNodeInserted and DOMNodeRemoved to detect when things have been added or removed from the toolbar that personal-bookmarks (aka bookmark toolbar items) is in because they are DOM mutation events, which slow Firefox down. In that bug we dealt with the case that the personal-bookmarks have been moved to the tabs toolbar and opening or closing tabs means the personal-bookmarks should be resized. When there is a more performant alternative to DOMNodeInserted and DOMNodeRemoved we should use them instead.
