Detect and block browser fingerprinting attempts by websites!
FingerprintAlert is a free open-source browser add-on that alerts you when websites you visit attempt to perform a new method of tracking called Browser Fingerprinting (to learn more about the subject, visit https://www.fingerprintable.org). The add-on also possesses a built-in option to block these attempts. The add-on monitors all http responses (e.g. POST and GET) that are relayed by a visited website for recognizable fingerprinting patterns.
