title: .fadeOut() in Firefox
body: <p>I've added a fadeOut() function to my element and when I inspect the element I actually see the numbers for opacity decrease, and when they come to 0, the element simply disappears, instead of slowly fading out. If that a FF bug?</p>
  
  <p>Here's my code</p>
  
  <pre><code>setTimeout(function () {  
      $('#myEm').toggleClass('in').delay('3000').fadeOut('slow',  function() {
             $(this).remove();
      });
  }, 100);
  </code></pre>
