title: file upload not working in firefox
body: <p>I have in my asp.net page</p>
  
  <pre><code>       &lt;input id="MyTextBox" runat="server" type="text" name="T1" size="20"/&gt;
  
         &lt;asp:Button ID="UploadFileButton" runat="server" Text="Upload"  /&gt; 
  
        &lt;input id="FileUpload" runat="server"  type="file"  style="height: 22px; visibility:hidden;" /&gt;
  </code></pre>
  
  <p>linked to JS script:</p>
  
  <pre><code>       $("#UploadFileButton").live("click", function(event) {
  
              event.preventDefault();
  
              $("#FileUpload").click();
  
         });
       $(function() {
         $('#FileUpload').change(function() {
                 $("#MyTextBox").val($(this).val());
          });
      });
  </code></pre>

  After the user chose a file the MyTextBox=Selct file path.</p>
