title: Firefox doesn't show the FontAwesome unicode
body: <p>The render of a FontAwesome icon works perfect on Firefox. But when I wanna change it through the inspector (Firebug), it doesn't show the unicode (for example: f066). So where I should have:</p>
  
  <pre><code>content:"\f066;
  </code></pre>
  
  <p>It shows:</p>
  
  <pre><code>content: "";
  </code></pre>
  
  <p>It is not showing the data correctly. If I overwrite a new one (\f077) it prints nothing. Is it possible to fix it? What I need is to be able to change FontAwesome icons from the inspector, like on Chrome.</p>
