title: CrossRider extension is not working on Internet Explorer 11
body: <p>We are using CrossRider to develop an extension for Internet Explorer. I added alerts in the background and in extension.js, but there are no alerts when I install this extension. What is the problem?</p>
  
  <p><strong>background.js</strong>:</p>
  
  <pre><code>appAPI.ready(function($) {
      alert("appAPI.platform = " + appAPI.platform);
  });
  </code></pre>
  
  <p><strong>extension.js</strong>:</p>
  
  <pre><code>appAPI.ready(function($) {
      alert("appAPI.platform = " + appAPI.platform);
  });
  </code></pre>
  
  <p>Our Extension ID is 43889. I'm using Internet Explorer 11 but this extension should work on all versions of Internet Explorer.</p>
