title: Why Sending multiple print by javascript is blocked with firefox and how to disable it?
body: <p>I'm sending three print statements.</p>
  
  <pre><code>PagePrint=window.open('xx');
  PagePrint.print();
  PagePrint.print();
  PagePrint.print();
  </code></pre>
  
  <p>the first print is done successfully but in the second statement <code>firefox</code> blocks printing and show this message:<code>(prevent this page from creating additional dialogs)</code>.
  How to disable this dialog using <code>firefox configuraton</code> or any other ways?</p>
