This article describes a feature available in Firefox 3.0, Clear Private Data, which allows you to delete all or part of your saved history.
This feature was updated in Firefox 3.5, and is now called Clear Recent History. In addition to being able to clear all or part of your saved history items, you can specify how much of your history is cleared (e.g. the last hour). To learn about this feature, see Delete browsing, search and download history on Firefox.
Firefox uses private data such as user names, history, and cookies, to enhance your experience on the internet.
Sometimes you may not want other users of your computer to see or access this information. You can clear your private data to prevent others from seeing or accessing it. This can be done manually, or you can set up Firefox to clear parts of your private data automatically.
