The Internet browser on the PlayStation 3 keeps a record of all the websites you have visited. Other people with access to the PS3 can check this log and see where you've been on the Internet. If you prefer to keep your browsing history private, you can delete the browser history on your PS3.
Open the "Internet Browser" program under the "Network" column of the PS3 main menu.
Press the "Triangle" button on the controller to open an options menu.
Go to "History" and press "X." This displays a list of the websites you have visited on your PS3.
Press "Triangle" to bring up another options menu.
Navigate to the "Delete All" option and press "X." Select "Yes" from the screen that pops up. Your Internet browsing history is now deleted.
Clearing your browsing history does not clear saved forms like account names or passwords.
