Defending against canvas fingerprinting by reporting a fake value.
"Canvas Fingerprint Defender" is a Firefox add-on that offers a unique layer of privacy protection.

Tested on https://browserleaks.com/ and works fine, I get a different canvas fingerprint ID each time I load a page :) Tested on https://webbrowsertools.com/canvas-fingerprint/ and same result, a different canvas fingerprint ID each time. However, this last website does detect that the canvas fingerprint is being spoofed. Detection can cause the website to ignore canvas fingerprint and use other methods to identify you instead. Therefore this extension is best used alongside protection against other types of fingerprinting. ilGur's other extensions work fine too (WebGL Fingerprint Defender, Font Fingerprint Defender, and AudioContext Fingerprint Defender) so I would recommend installing them as well.
