Comment 28 for bug 777619

It adds two widgets to the menubar (one of these is a toolbarspring and the other one is an empty box, according to DOM inspector). There's nothing I can do about that. I can't make globalmenu-extension hide the menubar when there are still other widgets on it, in case the user added them there deliberately. For Thunderbird, we have a hack to move the spinner on to the toolbar, but that's only because the spinner is on the menubar in the default profile.
