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.

Extension summary

WebGL Fingerprint Defender is a browser extension that let you easily hide your real WebGL fingerprint by reporting a random fake value.

According to many tech blogs, completely blocking WebGL API is not a good idea, therefore reporting a fake fingerprint could be the best solution to better protect your privacy. This add-on simply adds a small noise to the actual fingerprint and renews it every time you visit a website or reload a page.

With the browser's WebGL API, in general, two types of fingerprints can be generated. One with WebGL constants and the other with an image that is rendered with the WebGL API. This add-on can spoof both values at the same time.

To disable this add-on, please visit the extensions page in your browser and then click on the disable button. Please note that this add-on does not have any toolbar icon/button.

This extension is made in collaboration with the author of "Canvas Fingerprint Defender": https://chrome.google.com/webstore/detail/canvas-fingerprint-defend/lanfdkkpgfjfdikkncbnojekcppdebfp

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 !
