Some of these sites ask you to confirm that you want to leave the site. 
  Brain damaged ones even ask if you click on a link.  Dain bramaged 
ones will keep asking forever until you agree to stay on the site, to 
the point that you need to use kill -9 in a terminal to kill firefox 
completely.

If you've ever had a problem with that, here's what you do.  First, you 
bookmark a page.  When the dialog comes up, name it Escape, or whatever 
you think will remind you of what it's doing.  Replace the url with this:

javascript:window.onbeforeunload=null;document.body.onbeforeunload=null;window.onunload=null;document.body.onunload=null;window.onblur=null;document.body.onblur=null;window.onkeypress=null;window.onkeyup=null;document.body.onkeypress=null;document.body.onkeyup=null;document.body.outerHTML='<body>Try%20closing%20now.</body>';document.getElementsByTagName('head')[0].outerHTML='<head></head>';void%200;

Save the bookmark and go back to surfing.  The next time this happens, 
confirm that you want to leave; if it doesn't let you, click on this 
special bookmark.  Then, when the popup comes back, confirm that you 
want to leave and it will now let you.
