Anti-Fingerprinting Shield Plus – Advanced Privacy Protection

Anti-Fingerprinting Shield Plus enhances your online privacy by spoofing and blocking various browser fingerprinting techniques. It randomizes or disables elements like canvas, WebGL, audio context, language, timezone, CPU cores, screen dimensions, and sensor APIs to make your browser fingerprint less unique and more resistant to tracking.
