As you browse the web, Firefox helpfully remembers lots of information for you – sites you've visited, files you've downloaded and more. All of this information is called your history. However, if you are using a public computer or share a computer with someone, you may not want others to see these kinds of things.
This article explains what information is stored in your Firefox history and gives you step-by-step ways to clear all or part of it.
- To temporarily stop Firefox from storing history, see Private Browsing - Use Firefox without saving history.

What things are included in my history?
- Browsing & Download History: Browsing history is the list of sites you've visited that are shown in the History menu, the Library window's History list and the address bar autocomplete list. Download history is the list of files you've downloaded that are shown in the Downloads window.
- Form & Search History: Form history includes the items you've entered into web page forms for Form autocomplete. Search history includes items you've entered into the search field on the New Tab page or into Firefox's Search bar.
- Cookies: Cookies store information about websites you visit, such as site preferences or login status. This includes information and site preferences stored by the Adobe Flash plugin. Cookies can also be used by third parties to track you across sites. For more info about tracking, see How do I turn on the Do Not Track feature?. Note: In order to clear cookies set by Flash you must be using the latest version. See Updating Flash for instructions.
- Cache: The cache stores temporary files, such as web pages and other online media, that Firefox downloaded from the Internet to speed up loading of pages and sites you've already seen.
- Active Logins: If you have logged in to a website that uses HTTP authentication since you most recently opened Firefox, that site is considered "active". Clearing this logs you out of those sites.
- Offline Website Data: If you've allowed it, a website can store files on your computer so that you can continue to use it when you are not connected to the Internet.
- Site Preferences: Site-specific preferences, including the saved zoom level for sites, character encoding, and the permissions for sites (like pop-up blocker exceptions) described in the Page Info window.
