WebGL Fingerprint Defender

Defending against WebGL fingerprinting by reporting a fake value.

WebGL Fingerprint Defender - An Extension for Online Privacy

'WebGL Fingerprint Defender' is a unique Chrome extension designed to protect your privacy. It works by reporting a random fake WebGL fingerprint, thus shielding your actual fingerprint. Instead of completely blocking the WebGL API, it merely adds slight noise to the actual fingerprint and refreshes it with each site visit or page reload. It's able to spoof two types of WebGL fingerprints simultaneously - one with WebGL constants and the other with WebGL rendered images. To disable it, simply go to your browser extensions page.

It works perfectly for latest chrome, but can't work for Chrome 89 and above version. Since my browser can't upgrade to the new version due to some reasons, so I need this. Thanks for your nice extension !
