I don't know if the FF 4 beta 6 is the problem or the problem is of jQuery. Firefox 3.6.9 is ok. I will report this bug to Mozilla too.

Below is the code that not execute the ajax callback using json.

jQuery("#select_locale").live('change', function(){



function updateLocale(id){

jQuery.post('/index.php/delivery/pizzas/setlocale/', {'ID': id}, function(data){

alert('callback here');

}, 'json');

I can confirm this bug. jQuery 1.4.2 doesn't fire any ajax callbacks on Firefox 4 beta 6 while the older version 1.3.2 works fine. It also works fine on FF 3.6.10.

  • Status changed from new to closed
  • Resolution set to invalid

There is a  known compatibility issue with Firebug and all current Firefox 4 betas that causes XHR callbacks to not fire. Workaround is to switch off the "Show XMLHttpRequests" option in the Console panel.

Please follow the  bug reporting guidlines and use  jsFiddle when providing test cases and demonstrations instead of pasting the code in the ticket.
