Here are some of the operating systems FireFox has been ported to. Xandros Linux has the most realistic version of the Windows taskbar, while Mandrake has that half transparent Start Menu like Vista.
Funny how htese different Linux distros saw fit to borrow the Windows GUI pieces that never found their way into Mac OS X. Instead of a global menu that’s shared (and heavily altered) between the operating system and running applications, a hideable taskbar is a wonderful - and clearly understandable - thing. Note the positions of the close a window button, and also minimize and maximize.
