title: Using font-awesome in thunderbird signature
body: <p>Is it possible to use font-awesome in Thunderbird signatures? </p>
  
  <p>So far, I've tried embedding the code from <a href="http://fortawesome.github.io/Font-Awesome/get-started" rel="nofollow">fortawesome.github.io/Font-Awesome/get-started</a> in the HTML signature, as follows: </p>
  
  <pre><code>&lt;link href="//netdna.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet"&gt; &lt;i class="fa fa-map-marker"&gt;&lt;/i&gt; (Street Address here) &lt;i class="fa fa-phone"&gt;&lt;/i&gt; etc...
  </code></pre>
  
  <p>but this isn't working. Can someone explain what I'm doing wrong, or can it not be done?</p>
