Hi, I admire your persistence on this question however there is a bug that has the attachment that Gingerbread man referred to titled: "Bug 391834 - Don't allow alert/confirm/prompt in onbeforeunload, onunload and onpagehide"

This sounds like its disabled and you are trying to make it work. But you also already solved this with a batch file in this question https://support.mozilla.org/en-US/que.../993972?esab=a&s=&r=0&as=s So I will mark this as resolved.
