  <p>firebug shows me, in firefox:</p>
  <pre class="lang-css prettyprint-override"><code>.boxShadow {
    box-shadow: 3px 3px 5px #000;
  }
  </code></pre>
  <p>original css declarations:</p>
  <pre class="lang-css prettyprint-override"><code>.boxShadow {
    -webkit-box-shadow: 3px 3px 5px #000;
    -moz-box-shadow: 3px 3px 5px #000;
    box-shadow: 3px 3px 5px #000;
  }
  </code></pre>
  <p>how can i dislay selected element's browser specific css declarations in firebug ?</p>
