title: jQuery AJAX success doesn't work in Firefox
body: <p>I have this little AJAX call:</p>
  
  <pre><code>    $('#brick-mixer-form').submit(function(e) { 
          e.preventDefault();
  
          $("#mix-bricks-submit").addClass("load");
          $("#mix-bricks-submit").attr("value", "Blander sten..");
  
          var form_data = $("#brick-mixer-form").serialize()
  
          $.ajax({
             type: "GET",
             url: "build.php",
             data: form_data,
             dataType: 'text',
             async: false,
             success: function(data) {
                $(".active").attr('src', 'build.php?'+form_data+'').load(function() {
                $("#mix-bricks-submit").removeClass("load");
                $("#mix-bricks-submit").attr("value", "Bland igen");
                $("#bricks-selected").attr("value", form_data);
                $("#pdf_saver").css("display", "block");
             });
          }
       });
  });
  </code></pre>
  
  <p>In Google Chrome this works perfect, but in Firefox I can only trigger it once.</p>
  
  <p>When I press the submit button "<code>mix-bricks-submit</code>" again it will not run the call a second time.</p>
