title: ipython notebook requires javascript - on firefox web browser
body: <p>I'm trying to run jupyter notebook from a terminal on Xfce Ubuntu machine. 
  I typed in the command:</p>
  
  <p>jupyter notebook --browser=firefox</p>
  
  <p>The firefox browser opens, but it is empty and with the following error:</p>
  
  <p>"IPython Notebook requires JavaScript. Please enable it to proceed."</p>
  
  <p>I searched the web on how to enable JavaScript on Ipython NoteBook but didn't find an answer. I would appreciate a lot any help. Thanks!</p>
