SUP - Super Ultimate Privacy szerző: tripID

SUP (Super Ultimate Privacy) is a high-performance privacy extension designed to shield your online identity, block intrusive telemetry, and prevent cross-site tracking without breaking website layouts or functionality.

Built with a zero-data-collection philosophy, all processing occurs locally on your browser.

Key Features:

• Declarative Net Request (DNR) Blocker: Intercepts and blocks tracking domains, intrusive analytics scripts, and third-party trackers (Google Analytics, Facebook Pixel, Hotjar, Mixpanel, and more) at the network level.

• Non-Destructive Anti-Canvas Fingerprinting: Dynamically introduces subtle, offscreen noise into Canvas rendering methods (getImageData, toDataURL, toBlob), disrupting visual fingerprinting without breaking site UI, image editors, or QR code generators.

• WebGL & Hardware Masking: Spoofs WebGL GPU vendor/renderer strings via extension proxies while restricting system hardware enumeration (hardwareConcurrency, deviceMemory).

• Audio & Timezone Spoofing: Adds micro-scale random noise to AudioBuffer APIs to counter acoustic fingerprinting and normalizes the browser timezone output to UTC.

• WebRTC Leak Guard: Restricts non-proxied UDP traffic to prevent real local and public IP address leaks without impairing video conferencing services like Discord or Google Meet.

• Header Hardening: Automatically injects Do Not Track (DNT: 1) and Global Privacy Control (Sec-GPC: 1) headers alongside security enforcement headers (X-Content-Type-Options: nosniff, X-Frame-Options: SAMEORIGIN).

• Browser Hardening: Automatically disables network prediction, DNS prefetching, and hyperlink auditing (<a ping>).
