// @description    Inserts into a form a Mailinator alternate address corresponding to a Mailinator randomly generated secret address when the user presses F8 (the hotkey can be changed in the script). Two images are also added next to the input box. The first image links to the secret address mailbox and the other links to a RSS feed of the secret address mailbox.
