在FF地址栏里输入about:config 
在配置列表中找到 dom.allow_scripts_to_close_windows

点右键的选切换把上面的false修改为true

chrome里是可以的,firefox在window.open的才能用window.close

        <script type="text/javascript">
            var cls=document.getElementById("yes");
            cls.addEventListener("click",function(){
                if (navigator.userAgent.indexOf("Firefox") > 0) {  //ff打开一个空白页
                window.location.href = 'about:blank ';
                }else {                      //chrome关闭
                    window.opener = null; 
                    window.open('', '_self', '');
                    window.close();
                    // window.history.go(-1);
                }
            });
        </script>
