title: Can´t connect via JavaScript/Websockets with Firefox (after update?)
body: <p>I have an AngularJS App and I am using Websockets to connect to the Server:</p>
  
  <pre><code>_ws = new WebSocket("ws://localhost");
  </code></pre>
  
  <p>In FireFox I get now following error (FireBug):</p>
  
  <pre><code>The connection to ws://localhost/ was aborted, while the page was loading. (Translated by me from German).
  </code></pre>
  
  <p>It was always working, so I have the feeling the last Firefox update is causing the problem (current version: 37.0.1</p>
  
  <p>Its still working with all other Browser I tested with (Chrome, InternetExplorer, some mobile Browser on my Android).</p>
  
  <p>Anyone could know what the problem is here? Thank you very much!</p>
