As you browse the web, Firefox remembers lots of information for you - like the sites you've visited. There may be times, however, when you don't want people with access to your computer to see this information, such as when shopping for a present. Private Browsing allows you to browse the Internet without saving any information about which sites and pages you’ve visited.
Private Browsing also includes Tracking Protection, which prevents companies from tracking your browsing history across multiple sites. To learn more about Private Browsing with Tracking Protection in Firefox, see Tracking Protection.
We'll show you how it works.

Firefox is set to remember history by default but you can change this setting in your Firefox Privacy OptionsPreferences (click the Firefox menu , choose and select the panel). When you change your History setting to Never remember history, this is equivalent to always being in Private Browsing mode.
