title: Firefox ignores "video/quicktime" MIME Type for file input
body: <p>I have a form with a file input to handle file uploads for images or videos. I want to restrict the accepted file-types to <em>.jpg</em>, <em>.gif</em>, <em>.png</em>, <em>.mp4</em> and <em>.mov</em>, so I'm using the <code>accept</code> option on my <code>input type="file"</code> as follows:</p>
  
  <pre><code>&lt;input name="message[file]" accept="image/jpeg,image/png,image/gif,video/mp4,video/quicktime" type="file"&gt;
  </code></pre>
  
  <p>This works basically fine, but Firefox seems to ignore the <code>video/quicktime</code> MIME type and the file dialog box shows the <em>.mov</em> files as unavailable. All the other accepted file types are available.</p>
  
  <p>I can select the .mov files when I use <code>video/*</code> as accepted file-types, but I want to restrict the video-uploads to <em>.mp4</em> and <em>.mov</em>. According to my research <code>video/quicktime</code> is the correct MIME type for .mov files and the WebKit-Browsers work well with it. Why would Firefox not accept the .mov files?</p>
