title: How to disable automatic change of browser mode in IE9?
body: <p>How could I use IE9 with permanent "Browser mode" and "Document mode"?</p>
  
  <p>I want to use IE9 mode all the time, because I am developing an add-on that work only with IE9 mode, I need to force my browser to be in IE9 mode, instead of changing the mode again and again,
  Is there API for IE9 that allow me to set the mode?</p>
  
  <p>Thanks</p>
