title: firebug iframe breaking atmosphere iframe
body: <p>I have an invisible iframe that is talking to an atmosphere comet broadcaster. It works fine on most of the computers in the office. </p>
  
  <p>On one computer in the entire building it breaks. The problem seems to be that there is an iframe that somehow gets inserted on that machine:</p>
  
  <pre><code>&lt;iframe style="position: absolute; width: 5em; height: 10em; top: -10000px;" src="javascript:'
  &lt;html&gt;
  &lt;head&gt;
  &lt;script&gt;if("loadFirebugConsole" in window){window.loadFirebugConsole();}
  &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;/body&gt;
  &lt;/html&gt;'"&gt;
  &lt;/iframe&gt;
  </code></pre>
  
  <p>(note that most of this html is actually within the src for the opening iframe tag). </p>
  
  <p>That iframe blinks in and out of existence, and when it does it clobbers my iframe that's handling the comet service. </p>
  
  <p>I assume that this has something to do with firebug tools having been installed, but it happens on chrome as well as on firefox. </p>
  
  <p>Has anybody else come across a this behavior? </p>
