I'm using Firefox 4.0 and an addon called Personal Titlebar https://addons.mozilla.org/en-US/firefox/addon/personal-titlebar/ "Anything placed on Menu Bar will be moved to Title Bar." This is my situation http://img863.imageshack.us/f/ff4u.jpg/ I realise it may be as easy as adding a single line to userChrome.css (I know where to find it), but I have no experience with actually writing that line. Can any of you help me here? Help would be much appreciated
