title: event.toElement in IE8 and Firefox?
body: <p>I have noticed that in Chrome and IE9, for <code>onmouseout</code> events there is an <code>event.toElement</code> property (so you can determine which element the mouse is now pointing at).</p>
  
  <p>I can not find a comparable property in Firefox.</p>
  
  <p>Unfortunately I can not use jQuery to handle these events, I have to use native js.</p>
  
  <p>Any advice would be appreciated.</p>
