title: animated gifs freeze in firefox 4.0 and above
body: <p>I'm using jquery to preload an animated gif and later on inject a message with animated gif to the code.
  it used to work fine until release 4.0 of firefox. since then only the 1st frame is 
  showed and the animation is frozen. (it works fine on IE and chrome)</p>
  
  <p>I use:</p>
  
  <pre><code>$("&lt;img&gt;").attr("src",image);  // preload the image
  </code></pre>
  
  <p>And later on:</p>
  
  <pre><code>$(message).insertAfter(obj);  // inject animated gif and some text
  </code></pre>
  
  <p>[EDIT] Added jsfiddle example: <a href="http://jsfiddle.net/na2ku/35/" rel="noreferrer">http://jsfiddle.net/na2ku/35/</a></p>
