Private Browsing on Firefox OS

This feature is available in versions 2.2 and up. To find your version number, see What is my Firefox OS version?.

Private windows let you visit web pages or perform searches without saving your information. This feature is especially useful if you have to share your device with other people.

Warning: Private windows don't make you anonymous on the Internet. Your Internet service provider, employer (if using your employer's WiFi, for example), or the sites themselves can still track what pages you visit.
