Managing your web browsing History in the web browser Firefox is easy. First, open Firefox, then select History tab on the top menu bar of the browser. You select to view your browsing history in several different ways. You can choose to view all past browsing history or you can choose to just view one of the last seven days. You can also chose to view it as a side bar or a separate window. To clear your web browsing History, you can chose to delete just one page of the browsing history or you can also select an entire day, a month, or all of your history. To delete one page, select that page and then right-click. This will bring up a separate menu that offers you the ability to delete that one item. You can also select a day or a month and then right-click it and open the new menu and elect to delete it.
