title: Ajax sends empty POST-data but ONLY in IE and Firefox
body: <p>I have a strange problem (which I've searched for but with no success). I'm using Ajax to post a form to a PHP-script. This works fine in Chrome, Opera and Safari. However, in both IE and Firefox the form gets sent to the script correctly but with the form data missing. When the POST-data is missing, I've made sure that the script returns an error. I've tried to search for this problem for hours, but without any luck. You're my last hope.</p>
  
  <p>Here's the AJAX code (with some Javascript):</p>
  
  <pre><code>  &lt;script type="text/javascript"&gt;
    $(document).ready(function() {
  
    $("#latestNewsForm").on('submit', function(event) {
      event.preventDefault();
  
      $.ajax({
          url         : "http://devserver/site/php/getLatestArticles.php",
          type        : "POST",
          data        : new FormData(this),
          contentType : false,
          cache       : false,
          processData : false
      }).done(function (data) {
          $("#formResponse").html(data);
      });
  
     });
    });
    &lt;/script&gt;
  </code></pre>
  
  <p>And here's the form:</p>
  
  <pre><code>&lt;form id="latestNewsForm"  method="post"&gt;
      &lt;input type="submit" name="currentPage" id="firstPage" value="1"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>A BIG thanks in advance!</p>
