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. We'll show you how it works.

Important: Private Browsing doesn't make you anonymous on the Internet. Your Internet service provider, employer, or the sites themselves can still track what pages you visit. Private Browsing also doesn't protect you from keyloggers or spyware that may be installed on your computer.
