The following code shows fine in FireFox but IE 9 does not want to display the font. Is there something I can try?

```
<!DOCTYPE html>
<html>

<head>
  <link href="http://maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css" rel="stylesheet">
</head>

<body>
  <i class="fa fa-camera-retro"></i> fa-camera-retro
</body>

</html>

```
