Note that Firefox has a build-in way to disable the backspace key.

In beforeunload function i am unable get the event code.. wrote alert box for event keycode getting message as undefined
Need to disable following pop up (Please check attached image)
Your existing function could set a global flag that you check in the function that runs onbeforeunload; does that work?
I'm not aware of any way to get rid of the dialog.
