title: How do I keep FireFox from "spinning" with a long-polling request?
body: <p>I'm using the following for a long-polling request...</p>
  
  <pre><code>$.getJSON(url, function(data) {
       ...
  });
  </code></pre>
  
  <p>The request won't finish until either 30 seconds have passed or there is information to send (long-polling).</p>
  
  <p>The problem is that Firefox is the only browser that will display "Waiting for URL..." at the bottom.  Is there any way to prevent this?</p>
