Canvas Fingerprint Defender

Defending against Canvas fingerprinting by reporting a fake value.

Canvas Fingerprint Defender - Secure your Online Privacy

Canvas Fingerprint Defender is a lightweight Chrome extension designed to protect user privacy. It combats canvas fingerprinting, a common online tracking method, by reporting a random fake value instead of the real fingerprint. It's easy to use - just add to your browser and start browsing. This extension adds a small noise to the actual fingerprint and renews it every time a webpage is visited or refreshed. Tests can be conducted using websites that display your fingerprint, with every reload returning a fake fingerprint.

If you are using Brave browser like I am this does more harm than good. Brave (and lots of other browsers) has built in randomization, so adding an extension just makes your fingerprint stand out. If you are unsure, you can test your results at coveryourtracks.com

I spent TWO DAYS debugging my project because of this extension! Every image I drew on a canvas it was getting random colour tints. I was about to throw my pc out the window. Turns out, Canvas Fingerprint Defender was the cause of the issue. Disabled it, and poof - problem solved. This extension might be fine for privacy, but the side effects should be mentioned clearly. Save yourself the headache and disable it while coding.
