The Mozilla Foundation released the second beta of its Firefox 3.1
browser this week, adding a feature that allows the user to turn off
the application's normal recording of their online activities.
The feature, known as private browsing, allows a user to command the
program to ignore various digital bread crumbs. With the mode
activated, a browser will not store the history of sites a user visits,
memorize cookies or cache Web site content. The feature was a
relatively last minute feature to version 3.1 of the program.
