title: Select directory for HTML5 multiple file input in Firefox?
body: <p>I want to allow users to select a local directory on a webpage (and then read all the files in the directory).</p>
  
  <p>In Chrome I can add the <code>webkitdirectory</code> attribute to enable this functionality. According to a comment in <a href="https://stackoverflow.com/questions/5826286/how-do-i-use-google-chrome-11s-upload-folder-feature-in-my-own-code">this question</a> and an answer to <a href="https://stackoverflow.com/questions/5808448/how-to-pull-multiple-files-html5-jquery">this question</a> you should be able to do the same in firefox using <code>mozdirectory</code> but I am unable to get it to work.</p>
  
  <p>I have tried the following in Firefox with no luck (works in Chrome):</p>
  
  <pre><code> &lt;input type="file" id="files" name="files[]" multiple mozdirectory="" webkitdirectory="" directory="" /&gt;
  </code></pre>
  
  <p>My Firefox version is 10.0.</p>
  
  <p>Are there any way for a user to select a directory for input in Firefox without requiring an add-on on the client-side (like Flash)?</p>
