Microsoft Keyboard and Mouse Software that you install with Microsoft keyboard and mice, (latest version) allows you to disable your windows key so that you don't accidentally hit it when gaming. When I take advantage of this feature, I can no longer type in Firefox. Typing in Firefox is completely disabled. Other browsers, windows, applications work, but not Firefox. What is it about the windows key that firefox needs for typing. Strange problem, but annoying because I have to use a different browser while game. Certainly not a deal breaker, but kinda strange.
