Private Browsing - Use Firefox without saving history

Private Browsing automatically erases your browsing information, such as passwords, cookies and history, leaving no trace when you close out. New versions of Firefox also have Content Blocking (Tracking Protection)Content Blocking, which prevents hidden trackers from collecting your information across multiple sites and slowing your browsing down.

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.

What does Private Browsing not save?

  • Visited pages: No pages will be added to the list of sites in the History menu, the Library window's history list, or in the address bar drop-down list.
  • Form and Search Bar entries: Nothing you enter into text boxes on web pages or the Search bar will be saved for Form autocomplete.
  • Passwords: No new passwords will be saved.
  • Download List entries: No files you download will be listed in the Downloads Window after you turn off Private Browsing.
  • Cookies: Cookies store information about websites you visit such as site preferences, login status, and data used by plugins like Adobe Flash. Cookies can also be used by third parties to track you across websites. See How do I turn on the Do Not Track feature? for more information about tracking. Cookies set in private windows are held temporarily in memory, separate from regular window cookies, and discarded at the end of your private session (after the last private window is closed).
  • Cached Web Content and Offline Web Content and User Data: No temporary Internet files (cached files) or files that websites save for offline use will be saved.
Note:
  • New bookmarks you create while using Private Browsing will be saved.
  • Any files you download to your computer while using Private Browsing will be saved.

Can I set Firefox to always use Private Browsing?

Firefox is set to remember history by default but you can change this setting in your Firefox Privacy OptionsPreferences :

  1. Click the menu button New Fx Menu Fx57Menu and choose Options.Preferences.
  2. Select the Privacy & Security panel and go to the History section.
  3. Choose Never remember history from the drop-down menu.
    Fx60HistorySettings-UseCustom Fx63CustomHistory
    This is equivalent to always being in Private Browsing mode.
Important: When Firefox is set to Never remember history you won't see a purple mask at the top of each window, even though you are effectively in Private Browsing mode. To restore normal browsing, go to your Privacy & Security OptionsPreferences and set Firefox to Remember history.
