title: FontAwesome Firefox issues with certain fonts
body: <p>See screenshot: <a href="http://awesomescreenshot.com/0242jcea3a" rel="nofollow">http://awesomescreenshot.com/0242jcea3a</a></p>
  
  <p>Certain FontAwesome icons don't display in Firefox at all, but others do. To name a few of the ones that don't load:</p>
  
  <ul>
  <li>YouTube</li>
  <li>Vimeo</li>
  <li>Instagram </li>
  <li>Video Play Button</li>
  </ul>
  
  <p>We are using the latest CDN version (//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css). Running Firefox 28. The HTML page is charset UTF-8 also.</p>
  
  <p>No idea what's causing this, but it's a really annoying bug, especially when it works fine in Chrome and Safari etc.</p>
  
  <p>I've tried loading the font locally instead of over CDN, and unfortunately this didn't fix the issue. I've also tried the below htaccess code:</p>
  
  <pre><code>&lt;FilesMatch ".(ttf|otf|woff)$"&gt;
      Header set Access-Control-Allow-Origin "*"
  &lt;/FilesMatch&gt;
  </code></pre>
  
  <p>There are no security/console errors showing in Firefox either?</p>
  
  <p>Any help would be greatly appreciated :)</p>
