In order to provide more accurate cookie categorization capabilities, CookieBlock can be configured to record a history of all cookies encountered by the user while browsing the web. This history is separate from the browser-internal cookie storage, and serves to allow the extension to remember previous categorizations, and to keep track of cookie updates. The collected data is never shared with anyone or anything outside the extension.
