title: styling a menulist in xul
body: <p>Is there a way to style a menulist in XUL? </p>
  
  <p>I'm using this code but the image is appearing inside the dropdownlist and keeping the original style of the arrow.</p>
  
  <pre><code>menulist,menupopup{ 
      -moz-appearance: none !important;
      list-style-image: url("chrome://myExt/skin/images/lang.png") !important;
  </code></pre>
  
  <p>}</p>
  
  <p>Thanks in advance,</p>
