Browser fingerprint testers such as EFF’s Cover Your Tracks collect data points—user agent, screen resolution, installed fonts, canvas rendering, and more—to calculate how unique and trackable your browser is. They simulate tracker techniques and offer guidance on reducing fingerprintability by adjusting settings or using privacy-enhancing browsers.
