About Prism Shield: Browser Anti Fingerprint
Prism Shield is a powerful anti-fingerprinting extension that stops websites from tracking your browser's unique digital fingerprint.
Most websites you visit collect data about your browser and device — your User-Agent, Canvas rendering, WebGL info, fonts, timezone, screen resolution, and more. Unlike cookies, browser fingerprints cannot be cleared. Together, these create a unique identifier that can track you across the web without your consent. Prism Shield blocks this tracking by spoofing these values, keeping your real browser identity hidden.
Key Features:
- User-Agent & Platform Spoofing — Mask your browser identity and operating system
- Canvas Fingerprint Protection — Adds deterministic noise to canvas rendering
- WebGL & WebGPU Spoofing — Hide your real GPU and renderer information
- AudioContext Protection — Injects subtle noise into audio fingerprints
- Font Enumeration Blocking — Hides installed fonts, reports only common system fonts
- Timezone Spoofing — Spoof your timezone with Smart Opposite, Manual Selection, or Auto from IP
- WebRTC Leak Prevention — Blocks local IP exposure
- Screen Resolution & DPR Spoofing — Hide your real screen dimensions
- Touch Screen & CPU Performance Fingerprinting — Spoof touch support and CPU benchmarks
- Hardware Spoofing — Spoof CPU cores, device memory (RAM), and hardware concurrency
- Network Spoofing — Spoof connection type (4G/3G/WiFi) and network information
- Language & Locale Spoofing — Change your browser's language
- Battery Status API Spoofing — Spoof your battery percentage and charging status
- Plugin & MIME Type Enumeration — Spoof plugin & MIME type lists
- Do Not Track & GPC Signals — Send DNT and Global Privacy Control headers
- HTTP Header Modification — Spoof User-Agent, Accept-Language, and Client Hints headers
- Smart Toggle — Disable specific anti-fingerprint features individually
- Smart Whitelist — Disable protection on specific sites that need it
