Firefox OnBeforeUnload Fun!
So Kevin correctly pointed out that you can do the same onbeforeunload behavior in Firefox as you can in Internet Explorer. It does require a little bit of a tweak to use the DOM event model, though:
window.onbeforeunload = function (oEvent) {
oEvent.returnValue = "blah";
}
See, even JavaScript authors can learn something new every once in a while!

I think you wanna add:
if(!oEvent) oEvent = window.event;
to the above so it works in IE again
