title: Laravel not returning response after ajax call in firefox
body: <p>Basically the ajax call is made, status OK, response is returned in other browsers but in Firefox the http response isn't returned at all.</p>
  
  <pre><code>$.ajax({
      type    : "GET",
      url     : 'schools_courses_calendar/'+eventId+'/associate_spot/'+spotId,
      success : function(response) {
          //console.log(response) logs an 'empty string'
          table =  $('#school_upcoming_courses').dataTable();
          table.fnDraw();
          $('#confirm-associate #spot_id').val('');
          $('#confirm-associate #event_id').val('');
      },
      error   : function(data) {
          alert('Error!');
          //console.error(data);
      }
  })
  
  return \Response::json(array(
      'success' =&gt; true,
      'errors'  =&gt; '',
      'spot'    =&gt; $l_aResponse['body']['spot']
  ));
  </code></pre>
