Window: blur() method

The Window.blur() method does nothing.

[!NOTE] Historically, this method was the programmatic equivalent of the user shifting focus away from the current window. This behavior was removed due to hostile sites abusing this functionality. In Firefox, you can enable the old behavior with the dom.disable_window_flip preference.
