I believe it's doable... not necessarily the best case for usability...
however...
in order to work across both IE and firefox/moz you have to use two
event handlers. In moz, "onunload" can be cancelled
<body onunload="return confirm('Lose your work?');">
in IE, the onunload event doesn't fire until after the browser is
already closed, however, they have a prioprietary onbeforeunload event,
so you can use that one instead to do the same thing for IE. Iirc you
don't have to do any special checking or anything, just copy whatever
you put in onunload into onbeforeunload also and you'll get the result
you want.
I was asked to do this several years ago for a company in Ft Lauderdale.
