What is CanvasBlocker?
Blocks the JS-API for modifying canvas to prevent Canvas-Fingerprinting. Users can choose to block the canvas API entirely on some or all websites (which may break some websites) or just block or fake its fingerprinting-friendly readout API. The different block modes include:
Highlights
- Blocks the canvas 2D and WebGL APIs to prevent websites from using them for fingerprinting
- Allows faking the readout API to return a new random value each time it is called, the default setting
- Provides an option to ask for permission before allowing a website to use the canvas readout API
- Supports a whitelist and blacklist for websites to control canvas API access
- Blocks other "fingerprinting" APIs like audio, history, and window properties
