Firefox 3.5 Offers ‘Private Browsing’

Safari’s had it forever, but Ars Technica’s Ryan Paul does a nice job of describing the feature:

With a stroke at the keyboard, users can erect stiff privacy barriers that will prevent their Web surfing habits from penetrating the browser history and defiling the sensitive auto-completion system with incriminating data where it might arouse the suspicions of subsequent users.

Perfect.
