If you hide the developer tools window for that tab, the console object remains exposed for each page you navigate to. If you open a new tab, you must also open the developer tools for that tab in order for the console object to be exposed. The console object is not part of any standard and is an extension to the Document Object Model. Like other DOM objects, it is considered a host object and is not required to inherit from Object, nor its methods from Function, like native ECMAScript functions and objects do. This is the reason apply and call are undefined on those methods. In IE 9, most DOM objects were improved to inherit from native ECMAScript types. As the developer tools are considered an extension to IE (albeit, a built-in extension), they clearly didn't receive the same improvements as the rest of the DOM. For what it's worth, you can still use some Function.prototype methods on console methods with a little bind() magic: var lo
