The ctrl+shift+P keyboard shortcut in Mozilla Firefox which enables a browsing mode that does not record history. The, "P" apparently stands for, "private", but was obviously chosen for the mode being very, "porn" friendly.
I used to have to delete all of my private files and login information whenever I browsed the net for smut. It sucked having to sign in to all my frequently visited sites. Then I discovered ctrl+shift+porn
