Firefox obj.style.hasOwnProperty
<p>Just trying to figure out how to do basic feature detection in FF...</p>

<pre><code>var    obj = $( '&lt;div style="position:relative;top:10px;"&gt;&lt;/div&gt;' )
  , hasTop = ({}).hasOwnProperty.apply( obj[0].style, [ 'top' ] );

// chrome hasTop === true
//     FF hasTop === false
//     IE hasTop === true
</code></pre>

<p>Or, if it's easier, I'm specifically trying to detect <code>MozTransform</code> support.</p>
