history leak

The history leak tag covers discussions about browser vulnerabilities that allow websites to detect which sites a user has visited. A prominent example involves a marketer exploiting a decade-old browser flaw to test thousands of visited links per second, compiling user interests such as pregnancy, fertility, and credit repair. This technique, known as browser history sniffing, raises significant privacy concerns. The tag focuses on the technical aspects of the flaw, its exploitation by advertisers, and the implications for user privacy. It is relevant for users interested in browser security, online tracking, and privacy protection.
