FireFox console.log(window); DOM , .

Using console.dir(window);instead gives you a snapshot of the properties of the object in the runtime you specify that you requested. If you look, you can click the last instance of the “window” in your FireFox report console.dir(window);to see the properties associated with the window object during the function call.
