Learn what information is stored in your Firefox history and how to clear all or part of it if you are using a public or shared computer.

As you browse the Web, Firefox 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]]. __TOC__ = What information is 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 suggestions in Firefox|address bar autocomplete]] list. Download history is the list of files you've downloaded that are shown in the [[Where to find and manage downloaded files in Firefox|Downloads window]]. * '''Form & Search History''': Form history includes the items you've entered into web page forms for [[Control whether Firefox automatically fills in forms|Form autocomplete]]. Search history includes items you've entered into the search field on the [[About the New Tab page|New Tab page]] or into Firefox's [[Add the Search bar to your Firefox toolbar|Search bar]]. * '''Cookies''': [[Cookies - Information that websites store on your computer|Cookies]] store information about websites you visit, such as site preferences or login status. Cookies can also be used by third parties to track you across sites. See [[How do I turn on the Do-not-track feature?]] to learn more about tracking. * '''Active Logins''': If you entered a username and password for a site that uses [https://wikipedia.org/wiki/Basic_access_authentication HTTP basic authentication] since you last opened Firefox, that login is considered “active”. Clearing this will log you out of all sites that use this authentication method. It will not log you out of websites that use cookies to store login status.<!-- https://bugzilla.mozilla.org/show_bug.cgi?id=540516#c1 https://support.mozilla.org/en-US/questions/1362921#answer-1470984 https://support.mozilla.org/en-US/questions/960425 --> * '''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. For more information, see [[How to clear the Firefox cache]]. * '''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 [[Font size and zoom - increase the size of web pages|zoom]] level for sites, character encoding, and the permissions for sites (like pop-up blocker exceptions) described in the [[Firefox Page Info window#w_permissions|Page Info window]]. = How do I clear my history? = # [[Template:fx29menu]] # Click {menu History} and select {menu Clear Recent History…} # Select how much history you want to clear: #* Click the drop-down menu next to '''Time range to clear''' to choose how much of your history Firefox will clear (the last hour, the last two hours, the last four hours, the current day or everything). #;[[Image:fx100-ClearRecentHistory|width=450]] #* Use the check boxes to select what information you want to clear from your history.
