Window: close() method

The Window.close() method closes the current window, or the window on which it was called.

This method can only be called on windows that were opened by a script using the method, or on top-level windows that have a single history entry. If the window doesn't match these requirements, an error similar to this one appears in the console: Scripts may not close windows that were not opened by script.

Note also that close() has no effect when called on Window objects returned by HTMLIFrameElement.contentWindow.
