Fixed with Firefox Version 3.0.9. I don't know if is something
specifically related to the browser but yesterday it downloaded the
new version and installed, and problem solved. The data is actually
what i sended plus the js code:
$.ajax({
type: 'POST',
url: 'file.php',
dataType: 'json',
success: function(mensaje){
alert(dump(mensaje));
},
});
I use this for dump (maybe helps someone).

Thanks, I will use try again with a not updated firefox again and see
what's going on.
