Anti-Fingerprinting Shield Plus – Advanced Privacy Protection (AFS+)
Advanced browser fingerprint spoofing for better privacy and online anonymity.
Browser fingerprinting uses subtle data like your screen size, system language, canvas output, and GPU info to uniquely identify your device — even without cookies.
AFS+ fights this by spoofing or blocking many fingerprinting methods.
⸻
What it does:
• Spoofs navigator.language and navigator.languages
• Randomizes navigator.platform (Windows, Mac, Linux, etc.)
• Spoofs navigator.userAgent from a realistic set
• Randomizes hardwareConcurrency (CPU cores)
• Spoofs screen size (width, height, inner dimensions)
• Disables TouchEvent and ontouchstart
• Blocks battery API
• Blocks sensor APIs (motion/orientation)
• Blocks or spoofs mediaDevices.enumerateDevices
• Empties navigator.plugins
• Adds noise to canvas fingerprinting
• Spoofs WebGL vendor, renderer, texture size
• Adds noise to audio fingerprinting
• Blocks beforeunload traps
All values are randomized per session.

How to install:
1. Install a userscript manager:
• UserScripts (Firefox or Chromium)
• Tampermonkey
• Violentmonkey
2. Click the “Install this script” button above.
3. The script will activate on all pages.
You can modify the spoofed values in the script if you want to customize the fingerprint style.

Notes:
• This script does not protect against WebRTC leaks. Use uBlock Origin or browser settings to block them.
• Font fingerprinting is not blocked (only possible via extensions).
• A small number of websites may break or behave strangely due to blocked fingerprinting features.
