WebGL is a JavaScript API used to render 3D graphics within a web browser by utilizing the device's GPU. This makes it possible for websites to gather detailed information about a user's graphics card, which can be used to create a unique browser fingerprint.

WebGL in Chrome
-
To disable WebGL in Chrome, start the program with one of this command-line options:
--disable-webgl or --disable-3d-apis
This is valid for all Chromium-based web browsers.
WebGL in Firefox
-
To disable WebGL in Mozilla Firefox:
- Type
about:config in the address bar and press Enter.
- In the search bar, type
webgl.disabled and double-click the preference to set its value to true.
There is also few interesting properties that you can play with:
webgl.enable-debug-renderer-info
webgl.sanitize-unmasked-renderer
webgl.override-unmasked-renderer
webgl.override-unmasked-vendor
