Websites on the internet identify and collect information about users by so-called web tracking technology. To track user information, many websites save a small piece of data, embed invisible objects, or use accounts and hardware configuration.
To protect your privacy and security on the internet, various browser tools (Add-ons) exist to identify advertising tracking and other user surveillance technologies that website owners deploy on their sites.
