The close method closes only windows opened by JavaScript using the open method.
If you attempt to close any other window, a confirm is generated, which
lets the user choose whether the window closes.
This is a security feature to prevent "mail bombs" containing self.close().
However, if the window has only one document (the current one) in its
session history, the close is allowed without any confirm. This is a
special case for one-off windows that need to open other windows and
then dispose of themselves.
