title: Portable Document Format to Use Adobe Acrobat (in Firefox)
body: <p>How can I change the <a href="http://i.stack.imgur.com/RLYbm.jpg" rel="nofollow">Portable Document Format to Use Adobe Acrobat (in Firefox)</a>?</p>
  
  <p>Can we modify this in firefox.cfg/ *.ini file or any other way, instead manually changing in Firefox Options -> Application -> Portable Document Format -> Use Adobe Acrobat (in Firefox)</p>
