In the address bar, type "about:config" (with no quotes), and press Enter.
Click "I'll be careful, I promise".
In the search bar, search for "javascript.enabled" (with no quotes).
Right click the result named "javascript.enabled" and click "Toggle". JavaScript is now enabled.

I'm trying to run jupyter notebook from a terminal on Xfce Ubuntu machine. 
I typed in the command:
jupyter notebook --browser=firefox
The firefox browser opens, but it is empty and with the following error:
"IPython Notebook requires JavaScript. Please enable it to proceed."
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!
