I have the same issue on Hardy 32 bit with all updates: Firefox's window decoration disappears randomly, several times a day. (It actually disappeared when I navigated to this page here.)
My workaround is to hit F11 (full screen) twice. The first activates full-screen mode, and the second deactivates it again, at which point the window gets its decoration back.
