//这个在线客服在火狐下不能滚不， 解决方案是:
 
 1 if (verticalpos == "fromtop") {
 2                 var pY = ns ? pageYOffset: document.documentElement.scrollTop;
 3                 ftlObj.y += (pY + startY - ftlObj.y) / 8;
 4             } else {
 5                 var pY = ns ? pageYOffset + innerHeight: 
document.documentElement.scrollTop + 
document.documentElement.clientHeight;
 6                 ftlObj.y += (pY - startY - ftlObj.y) / 8;
 7             }
 
 第6行后加一句： ftlObj.style.top=ftlObj.y+"px";
