hi,

i want dynamically replace Castle Age's (facebook game) favicon, but
strangely favicon doesn't change!

where am i wrong?? here is the code:

// ==UserScript==
// @name           FB Castle Age
// @namespace      http://apps.facebook.com/castle_age/
// @include        http://apps.facebook.com/castle_age/*
// ==/UserScript==
var head=document.getElementsByTagName("head")[0];

var ico={
        e:document.createElement("link")
}
ico.e.id="ico_e";ico.e.rel="icon";ico.e.type="image/png";
ico.e.href="http://www.rw-designer.com/icon-image/273-16x16x32.png";;

var getTimers=function(){
        // energy
        var t=document.getElementById
("app46755028429_energy_time_value").innerHTML;
        var M=document.getElementById
("app46755028429_st_2_2").getElementsByTagName("span")[1].innerHTML;
        var c=document.getElementById
("app46755028429_energy_current_value").innerHTML;
        document.title=t+" "+c+"/"+M;

        var links=document.getElementsByTagName("link");
        for(var i=0;i<links.length;i++){
                var link=links[i];
                if(link.rel=="shortcut icon"||link.rel=="icon"){
                        head.removeChild(link);
                }
        }

        head.appendChild(ico.e);
        setTimeout(getTimers,1000);
}
getTimers();
