Capturing key and mouse events in FF8 and later

I have been using the nsIDOMKeyListener, nsIDOMMouseListener and
nsIDOMUIListener but they seem to have been removed as of FF8 version
8.
I would like to know how to get register callbacks for Key and Mouse
events now the above interfaces are gone. I think that for the Key
stuff I might need to use nsINativeKeyBindings, but I can't finde
anywhare in developer release notes or otherwise how to do this.
