Jquery Error and CI on FF3

Guys cheers! it is resolved, and thanx to Bramme for some idea, but this issue can be solved by JSON, getJSON();

Regarding more clarification, i was using $.post(url,data,function,'json');
Now i am using $.getJSON(url, data, function);

And its running fine, in a cross domain nature.
