>One more note is that for the xbox 360 controller, xinput is not used or not seen, but with a generic logitech (model F310) controller, Firefox picks up the commands and works as expected.
The F310 has a switch on the backside that supports both DirectInput and XInput (i.e. Xbox360 mode). It might be worth checking if it's in XInput mode.
