  if(navigator.userAgent.indexOf("MSIE") > 0){
    if(navigator.userAgent.indexOf("MSIE 6.0") > 0) {
            window.opener = null;
            window.close();
    } else {
            window.open('', '_top');
            window.top.close();
     }
    } else if (navigator.userAgent.indexOf("Firefox") > 0) {
            window.location.href='about:blank';
    } else {
            window.opener = null;
            window.open('','_self', '');
            window.close();
    }

setTimeout(function(){
