如何在Firefox的同一选项卡中打开弹出窗口

Question

在chrome中可以正常工作。窗口在右下角的同一选项卡中打开。但是在Firefox中，它会在新标签页中打开。

$(".ancChatBot").click(function () {
                height = 400;
                width = 400;
                var t = window.innerHeight - height + 40;
                var l = window.innerWidth - width - 12;                
                var popup_window = window.open("/_chatbotpopup.html", "", "height=" + height + ", width=" + width + ", left=" + l + ", top=" + t + ",menubar=no,location=no,resizable=yes,scrollbars=yes,status=no");

            });
