title: firefox 3.x doesn't support background images in Pseudo-classes?
body: <p>Is it a bug that Firefox doesn't seem to support background-image swapping in pseudo-classes or is it that the other browsers are doing more than they should be?</p>
  
  <p>I'm trying to figure out if I'm doing something wrong... this works in Opera and Chrome (haven't tested in IE yet)...</p>
  
  <pre><code>.myClass{
    background-image:url('off.jpg');
  }
  
  .myClass:hover{
    background-image:url('on.jpg');
  }
  </code></pre>
  
  <p>However firefox just ignores this.  I was hoping to avoid writing a javascript roll-over... this seemed like such an elegant solution, but I'm starting to suspect that I'm hosed.</p>
