Prism Shield: Browser Anti Fingerprint

Stop browser fingerprinting. Spoof User-Agent, Canvas, WebGL, WebGPU, Audio, Fonts, Timezone, Screen, Language & more.

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.
