I have seen that firebug is not showing json tab when calling $.ajax with async = false
Is this a jquery error or a firebug one?

The code is

1. $.ajax({
               async: false,
               dataType: 'json',
               success: function(data) {
                   dateFormat = data.date_format;
   
                   translations = jUI.Utilities.merge(translations, data.translations);
               },
               url: '/contacts/data'
           });
   
   
   
   
   
   
   
   
   

But if I make the call with "async: true", then the tab is visible again.

Thanks
