Remove the options to open bookmarks in tabs.
It's good thing to quit something that is not used.
But i suggest you to put this before the rest of yr code:@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
That line makes the code execute only for firefox browser chrome and it wont do for normal html web pages.
(It's possible that somewhere in the web there is a "#personal-bookmarks .openintabs-menuseparator" selector)
Is it meant to hide the option as well or just disable it?
Does what it says.
