我可以在Firefox Developer控制台中默认显示对象的类型吗？

Question

在Firefox Developer Edition（OSX上的44.0a2（2015-11-14））中，如果我在控制台中console.log一个对象，它看起来像这样：

Object { firstName: "John", lastName: "Doe", language: "en" }

有没有办法让Firefox javascript控制台显示Object的类型而不仅仅是'Object'？ Chrome开发者工具具有此功能并显示：

G…r.init {firstName: "John", lastName: "Doe", language: "en"}

代码：

(function(global, $) {

    var Greetr = function(firstName, lastName, language) {
        return new Greetr.init(firstName, lastName, language);   
    }

    Greetr.prototype = {};

    Greetr.init = function(firstName, lastName, language) {

        var self = this;
        self.firstName = firstName || '';
        self.lastName = lastName || '';
        self.language = language || 'en';

    }

    Greetr.init.prototype = Greetr.prototype;

    global.Greetr = global.G$ = Greetr;

}(window, jQuery));


var g = G$('John', 'Doe');
console.log(g);
