You can close all the tabs except for the last one which means you have to manually close the window instead of using a keyboard shortcut to do so. Reproducible: Always Steps to Reproduce: 1. Enable 'always show tab bar' 2. open tabs 3. try to close all the tabs using command+w and then try and close the last one, closing the window. It doesn't work Actual Results: You find yourself unable to close the main window with a keyboard shortcut without quitting the application Expected Results: it should have closed the main window, as it does when the tab bar isn't always displayed

This was fixed after Firefox 3 Beta 3 in bug 348031. FWIW, even if it hadn't been fixed, you would have been able to close the window with Cmd+Shift+W.
