Hotkey to close Firefox (and maybe other windows)
 

:curious:

Has anyone been typing along in Firefox and accidentally mis-hit a key and have the application suddenly close? I'm thinking there's a hotkey set to automatically close the current application window (or at least Firefox) but haven't been able to determine what it is and it's happened 3 times already...really annoying. I think the combo is a couple of keys near the bottom of the keyboard near your pinky fingers.

ive seen it too. But i dont think its a hotkey. I think its a bug. It could also be the webpage your visiting. It happens to me at very random times. It happens enough to be very annoying but not enough to figure out how to reproduce it.
