title: Firefox not able to find iframe
body: <p>This is the iframe I'm trying to access:</p>
  
  <pre><code> &lt;div class="mceBody" id="additionalTxt_b"&gt;
          &lt;iframe frameborder="0" id="additionalTxt_f" src='javascript:""' class="punymce"/&gt;
   &lt;/div&gt;
  </code></pre>
  
  <p>Using this line:</p>
  
  <pre><code>frames['additionalTxt_f'].document.getElementsByTagName("body")[0].innerHTML
  </code></pre>
  
  <p>For some reason I'm getting "frames.additionalTxt_f is undefined" from firebug.
  I have similar iframes (dynamically created by punyMCE plugin) on other pages, and they work perfectly fine. And IE7/8 has no problem accessing this iframe either.</p>
  
  <p>Just at a complete loss here. Any ideas on why Firefox can't find the iframe?</p>
