I have the same issue on a lenovo X61 laptop (intel video) using the latest karmic release. Full screen always uses the external monitor and only increases to a size that appears to be the one of the laptop screen. I would assume this bug is actually in the flash plugin and not firefox. The optimum behavior would be what totem does, of going totally fullscreen in whatever screen the window is currently in.
