title: View js files in firefox
body: <p>Everytime I try to navigate to a JS file on Firefox I get a save-as dialog. I would like to just be able to view the source in the actual browser and not have to download and open the file in another editor. </p>
  
  <p>Is there any way I can force Firefox to view the files?</p>
