title: Uploadify browser compatibility issue
body: <p>I am using uploadify plugin for allowing users to upload files to my website. The script works fine in chrome but does not work in ie and firefox</p>
  
  <pre><code>  $(function() {
      $('#file_upload').uploadify({
       'checkExisting' : 'check-exists.php',
      'buttonText' : 'Select project',
      'fileSizeLimit' : '163840KB',
       'fileTypeDesc' : 'Image Files',
      'fileTypeExts' : '*.zip; *.rar',
          'swf'      : 'uploadify.swf',
          'uploader' : 'uploadify.php',
          'onUploadError' : function(file, errorCode, errorMsg, errorString) {
           $("input[type=submit]").attr("disabled", "disabled");
  alert('The file ' + file.name + ' could not be uploaded: ' + errorString);
          },
          'onUploadSuccess' : function(file, data, response) {
              $("input[type=submit]").removeAttr("disabled");
      },
  
      });
  </code></pre>
