Inside a menu like that, firefox has grabbed the keyboard (and probly mouse).  This prevents other applications from getting input. It's a condition of X Windows where an app can steal the input and hold onto it if it wishes.  And this is how GTK+ menus work.  Noone else can grab in the meantime or release it for firefox.
