EFF’s Cover Your Tracks: Test Browser Fingerprinting and Tracking Protection

Cover Your Tracks is a project developed by the Electronic Frontier Foundation (EFF) designed to help users understand how websites and trackers perceive their browser. When visiting a site, browsers send requests that can reveal unique characteristics through fingerprinting techniques, allowing third parties to identify and track users across the web even without cookies. The tool analyzes various browser attributes such as fonts, screen resolution, plugins, and more to determine uniqueness and provide a detailed report on tracking protection levels. It educates users on the balance between privacy and convenience, demonstrating how protections like blocking trackers or using privacy-focused browsers affect visibility. The project also serves as research to evaluate the effectiveness of privacy add-ons and techniques used by trackers. Users can test their browser directly on the site to receive personalized insights, encouraging better privacy practices in an era of pervasive online surveillance. By highlighting potential vulnerabilities, it empowers individuals to take steps toward greater anonymity online without needing advanced technical knowledge.
