title: Crash firefox using JavaScript
body: <p>I'm part of a testing team and have been tasked with "behaving badly" using JavaScript in a Firefox browser.  I've tried <a href="http://www.yuki-onna.co.uk/browserdeath.html" rel="nofollow noreferrer">these methods</a> to take the browser down, but none of them do anything worse than cause a popup asking to shut down the script.</p>
  
  <p>Any other ideas?</p>
