title: Firefox not recognizing a font
body: <p>I'm styling the <code>pre</code> HTML element via CSS like this:</p>
  
  <pre><code>pre {
      font-family : "Franklin Gothic Medium","Arial Narrow Bold","Arial",sans-serif;
  }
  </code></pre>
  
  <p>And it works in Chrome/Chromium, Opera, Safari and IE (meaning that the font is indeed installed in the computer), but not in Firefox. Firefox only recognizes <code>Arial</code>.</p>
  
  <p>And I've tried with other custom fonts (like <code>Century Gothic</code>) and it works, so it's able to recognize custom fonts.</p>
  
  <p>Bottom line, Firefox isn't recognizing <code>Franklin Gothic Medium</code> nor <code>Arial Narrow Bold</code> even though</p>
  
  <ul>
  <li>they are installed in the computer</li>
  <li>it's able to recognize other custom fonts</li>
  </ul>
  
  <p>What might be going on here?</p>
