title: FireFox 3.6 - 9 drops favicon when changing window.location
body: <p><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=519028" rel="noreferrer">Problem</a> exists only on FireFox (from 3.6 up to current 9), other browsers are fine. My code looks like this:</p>
  
  <pre><code>jQuery.extend({
      AnchorFromUrl : function(url) {
          var anchor = url.substr(1).replace('.html','');
          $.fizzer_anchor = anchor;
          window.location.hash = anchor;
          return anchor;
      }
  });
  </code></pre>
  
  <p>The most weird thing is that if I place an alert before the window.location.hash = anchor; line, after clicking Ok favicon doesn't disappear, remove that alert() and you get your favicon disappearing.</p>
  
  <p>Note: it also drops the favicon if you just do <code>window.location = something</code>.</p>
