title: Firefox Websocket security issue
body: <p>We have a websocket server on port 8080 setup on a Linode box. Chrome and Opera work just fine. Firefox however complains that the operation is insecure.</p>
  
  <p>"The operation is insecure: Code 18"</p>
  
  <p>If I try to create a new WebSocket object in the web console before the page is loaded everything is fine. However, after the page loads something is screwy then I cannot create the object anymore. See the attached screenshot.<img src="https://i.stack.imgur.com/svwQc.png" alt="enter image description here"></p>
  
  <p>I have no idea what operation is insecure or even how to go about diagnosing this.</p>
