Are you sure about your code sample...Check again the source you copied from...
Your problem is not clear to me...Do you see the confirmation message (any) in Firefox?

The "beforeunload" event is very restrictive. In IE / Edge, all you can do is display a custom message by returning it from the event handler. In Firefox and Chrome, you can't even do that - any custom message you return will be ignored, and the browser will display its standard "data may be lost" message instead.

You certainly can't open windows or display modal dialogs. If you could, every malicious site on the Internet would do it to prevent you from leaving the page.

Stick with returning a simple string from your event handler. Browsers which allow it will display your message, and those that don't will display a standard message instead.
