<script type="text/javascript">
 var myclose = false;
 function ConfirmClose()         
 {                 
  if (event.clientY < 0)
   {                         
   event.returnValue = 'Any message you want';
   setTimeout('myclose=false',100);
   myclose=true;                 
}         
}

If you are trying to display a pop up when the user tries to navigate away from the page it is possible and there is even a cross browser solution. But if, what you are trying to do is making a call from javascript to see if firefox is exiting, I dont think that is possible from javascript...then again I might be wrong.

function goodbye(e) {
    if(!e) e = window.event;
    //e.cancelBubble is supported by IE - this will kill the bubbling process.
    e.cancelBubble = true;
    e.returnValue = 'You sure you want to leave?';

    //e.stopPropagation works in Firefox.
    if (e.stopPropagation) {
        e.stopPropagation();
        e.preventDefault();
    }
}
window.onbeforeunload=goodbye;
