## Description

Privatus is a professional-grade privacy and security extension that mitigates 156 attack vectors directly in your browser — no cloud, no telemetry, all local.

<strong>Tracker &amp; Malware Blocking</strong>
Integrates 70+ blocklists (EasyList, uBlock, Hagezi, OISD, Disconnect, Brave, and more) using Bloom Filters for O(1) lookups at only 5.7 MB of memory. Blocks ads, trackers, malware, phishing, cryptominers, and scam sites.

<strong>Anti-Fingerprinting with Privacy Budget</strong>
W3C-compliant entropy tracking across 20 APIs (Canvas, WebGL, WebGPU, AudioContext, fonts, WebRTC, sensors). Configurable budget (4–32 bits/session) with automatic noise injection when exceeded.

<strong>DNS-over-HTTPS</strong>
Built-in support for Cloudflare, Quad9, NextDNS, AdGuard DNS, and Control D. Includes DNS leak detection and automatic fallback on high latency.

<strong>Password Breach Protection</strong>
HIBP k-anonymity: checks passwords using only the first 5 SHA-1 characters — your password never leaves your browser.

<strong>Certificate Transparency Monitoring</strong>
Real-time <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/6d2f6901a05aceb5ecd44b627c6c02b31e02071568a0acb1f3fb3b64a93431a4/http%3A//crt.sh" rel="nofollow">crt.sh</a> monitoring detects unauthorized SSL certificate issuance for domains you visit.

<strong>SRI-Plus Supply Chain Integrity</strong>
Verifies SHA-256 hashes of 100+ popular CDN libraries (React, Vue, jQuery, Angular…) and alerts on mismatches or known CVEs.

<strong>Advanced Threat Detection</strong>
Detects Browser-in-Browser (BitB) attacks, WebCodecs exfiltration, Speculation Rules abuse, Import Maps hijacking, prototype pollution (Magecart patterns), and side-channel attacks (Spectre/cache timing/XS-Leaks).

<strong>Smart Context-Aware Profiles</strong>
Six profiles auto-select based on context: Normal, Strict, Paranoia, Banking, Developer, and Corporate. Includes per-domain whitelist and temporary 1-hour pause.

<strong>GDPR Compliant — Full User Rights</strong>
All data stored locally (no external servers). Supports data export, rectification, and complete deletion. Privacy by design (Article 25).

<strong>Multilingual</strong>
Available in English, Spanish, German, Arabic, Japanese, Russian, and Simplified Chinese.
