title: Firefox 30 is not hiding select box arrows anymore
body: <p>I have always used the "trick":</p>
  
  <pre><code>select {
      -moz-appearance: none;
      text-indent: 0.01px;
      text-overflow: '';
  }
  </code></pre>
  
  <p>to do custom select boxes on FF but since version 30 is released this stopped working completely. I have tried to find if this was deprecated but couldn't find anything. Is there a workaround, or another method to replace this?</p>
