What websites can see about you
Browser fingerprinting is a tracking technique that collects information about your browser, operating system, installed plugins, screen resolution, timezone, language settings, and other characteristics to create a unique identifier. Unlike cookies, fingerprints are difficult to delete because they are based on your device's configuration rather than stored data.
To reduce browser fingerprinting: use the Tor Browser which standardizes fingerprint attributes, enable Firefox's Enhanced Tracking Protection in strict mode, use browser extensions like uBlock Origin or Canvas Blocker, disable JavaScript for untrusted sites, use a VPN to mask your IP, and avoid installing unusual browser plugins or fonts that make your configuration more unique.
Yes, browser fingerprinting can track you across websites without cookies. Studies show that most browsers have a unique fingerprint, making it possible to identify and follow your activity. Advertisers and analytics companies use fingerprinting as a fallback when cookies are blocked. However, fingerprints can change when you update your browser or OS, making long-term tracking less reliable.
