title: Running firefox on Ubuntu
body: <p>So I have a server which I always log into via ssh. I am using selenium to scrape a website and am attempting to get firefox running via command line. When I run firefox, I get the following error:</p>
  
  <pre><code>    gksu ./firefox &lt;br&gt;**
      No protocol specified
  
     (gksu:28027): Gtk-WARNING **: cannot open display: :0
  </code></pre>
  
  <p>I have my display variable set to :0, do I need to run the x11 server? just generally confused any feedback appreciated...</p>
