somewhere in this chunk of code:
function refresh(){for(var b=_n("toast"),a=0;a<b.length;a++)1b[a].getAttribute("old")?container.removeChild(b[a]):b[a].setAttribute("old",!0);var d=new XMLHttpRequest;d.open("GET","/qresearch/threads.json",!0);d.onreadystatechange=function(){if(4=d.readyState&&200==d.status){var a=JSON.parse(d.responseText);find_recent_bread(a)}};d.send();trips()}
d.open("GET","/qresearch/threads.json",!0)
^^^ is the place where the json is pulled, and somewhere in there is where to add the referrer stuff?
