Clear browser data with Norton Utilities Ultimate
Norton Utilities Ultimate cleans the browser data in your web browser. To view the list of supported browsers, click here.
Norton Utilities Ultimate helps you clean the following categories of browser data:
-
Browsing History: The history of websites that you visited.
-
Browser Cache: A temporary storage location that stores downloaded files (for example, picture files from websites) to help the website load faster when you revisit.
-
Tracking & Other Cookies: These are data files that record information about the websites you visit.
-
Download History: The history of downloaded files from your browser (this option only removes the list of files and does not delete any files stored on your Windows PC).
If you do not want Norton Utilities Ultimate to clear login details of certain websites, you can create exceptions for such websites. You can add those websites to the Cookie Allowlist. For example, you may want your browser to autofill your Norton account login credentials. In this case, you can add my.norton.com to the Cookie Allowlist. This ensures your login details remain saved after a browser data clean-up session.
Windows
