With the following function below, I can send the data via ajax quietly in Chrome, but when testing in Firefox, no error occurs and the data is not sent.
$('#form_lista_amiga').validate({
    rules : {
        cpf: { required: true, cpf: true }
    },
    submitHandler: function(form) {
        var data = $( form ).serialize();
        event.preventDefault();
        $.ajax({
            url: "<?php echo Router::url(array('controller' => 'ListaAmiga', 'action' =>'add'), true); ?>",
            type: 'POST',
            datatype: 'json',
            data: data,
            success: function(data){
                $('#lista_amiga_msg').html(data);
                // alert(data);
            }
        });  
        return false;   
    }
});
What error happens when you try to send in Firefox? Could you please tell us?

Can you create an example in jsFiddle that has the problem you refer to? (or maybe @Paulohdsousa?)
