[jQuery] jquery form plugin and firebug conflict


Hi,
I am using Jquery form plugin to interact with PHP server code. When
firebug is on, the code correctly sends the data and processes the
reply from the server in Json format.
Here's the code:
            var options = {
            beforeSubmit: showRequest, // pre-submit callback
            success: processJson, // post-submit callback
            dataType:      'json',
            target: '#feedback',
            clearForm:     true
            };
            //form submit
            $('#create_project_fm').ajaxSubmit(options);
function process(data){
console.log("process");
if (data.error== "") {
window.location.reload(true);
     } else if(data.error!="") {
          $('#feedback').addClass('error');
          $('#feedback').text('error: ' + data.error + '');
     }else {
     //feedback here
     $('#feedback').addClass('success');
     $('#feedback').text('error: ' + data.feedback + '');
     }
}
However, I have noticed that when I turn Firebug off, the server code
prints out the echo statement instead of this being parsed by the
javascript function "process" as Json.
Any help would be really appreciated.
