Not sure if they work on FF4 (yet), but there are add-ons for that, of course. I don't mind losing the title bar, since I've long been in the habit of alt+dragging to move windows anyway. (This is a linux-ism, but well worth installing 3rd party software on OSX/Windows for -- particularly for alt + middle/right-button resizing: no need to screw around landing your mouse on a corner of the window.)
