title: Programmatically detect Mixed Content blocking in Chrome
body: <p>Does anyone know if it's possible to detect in JavaScript that Chrome has blocked content due to the Mixed Content restriction? I see that there is an error message in the Console, but this doesn't seem to be an exception, since using try/catch doesn't catch anything..</p>
  
  <p>So the question is, how to detect that content has been blocked?</p>
  
  <p>Thanks!</p>
