title: Google maps embed error in firefox
body: <p>I am using google maps Embed code to integrate multipin locations of a map.</p>
  
  <pre><code>&lt;iframe src="https://www.google.com/maps/d/embed?mid=zsjXv3NS8g6Y.krO7DAwRdcZk" height="480" width="640"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>The map is rendering properly in all other browsers with cross origin reference error.(even in IE7 with old version warning)</p>
  
  <p>This is the message I see on chrome and IE</p>
  
  <blockquote>

  <p>but in firefox theres a different error and map does not load.</p>
  
  <blockquote>
    <p>ReferenceError: _startApp is not defined
    <a href="https://www.google.com/maps/d/embed?mid=zsjXv3NS8g6Y.krO7DAwRdcZk" rel="nofollow">https://www.google.com/maps/d/embed?mid=zsjXv3NS8g6Y.krO7DAwRdcZk</a>
    Line 7</p>
  </blockquote>
  
  <p>This is an embed code to which i can't modify. Any solutions?</p>
  
  <p>EDIT: iframe is loading without map but clearly script in the iframe is breaking causing this error.</p>
