uBlock Origin Lite blocks ads and trackers brilliantly. But your privacy requires more than filter lists. PII Fortress is the all-in-one privacy suite that picks up where ad blockers leave off.
Works alongside uBlock Origin Lite · No account required
uBlock Origin Lite is one of the best ad blockers available, with over 16 million users and the same filter lists we use (EasyList, EasyPrivacy, Peter Lowe's). But ad blocking is a single layer in a multi-layered threat landscape.
Ad blockers hide some banners but rarely reject them properly. PII Fortress auto-detects and rejects consent across 22+ CMP frameworks before you see the popup.
Canvas, WebGL, AudioContext, font enumeration — sites build a unique ID even without cookies. Ad blockers don't address this. PII Fortress actively shields your fingerprint surface.
Filter lists block known ad domains, not newly registered scam pages. PII Fortress runs real-time scam scanning against Safe Browsing data to warn you before you interact.
If your email appears in a breach, no ad blocker will tell you. PII Fortress checks against the Have I Been Pwned database and alerts you to compromised accounts.
URLs are loaded with fbclid,
utm_*,
gclid, and dozens more tracking params.
PII Fortress strips them automatically on every navigation.
As AI tools become embedded in browsers, prompt injection is a growing vector. PII Fortress is the first extension to detect and flag prompt injection attempts in page content.
We use the same core filter lists as uBlock Origin Lite. The difference is what we build on top of them.

Comparison based on publicly available feature lists as of March 2026. uBlock Origin Lite remains the gold standard for MV3 ad blocking.
PII Fortress is not a replacement for uBlock Origin Lite — it is a companion. Chrome's Declarative Net Request API merges rulesets from multiple extensions, so both can run simultaneously without conflict.
Chrome's MV3 architecture allows multiple extensions to register declarativeNetRequest rules. Our 170,208 rules and uBOL's rules coexist without overriding each other.
uBOL handles ad blocking. PII Fortress handles cookie consent, fingerprinting, breach monitoring, scam detection, and everything else. Different responsibilities, zero duplication issues.
We use EasyList, EasyPrivacy, and Peter Lowe's — the same lists uBOL uses. If you run both, Chrome deduplicates matching rules automatically. No performance penalty.
These capabilities exist in PII Fortress alone — not in uBlock Origin Lite, not in Ghostery, not in any other single extension.
Covers 22+ Consent Management Platforms including OneTrust, Cookiebot, TrustArc, Didomi, and Quantcast. Rejects non-essential cookies before the banner even renders.
Actively randomizes Canvas, WebGL, AudioContext, and font enumeration outputs. Prevents cross-site fingerprint tracking without breaking page functionality.
Scans page content for hidden instructions designed to manipulate AI tools and LLM-powered browser features. A first-of-its-kind defense as AI integrates deeper into browsing.
Every page gets a 0–100 privacy score based on trackers detected, cookies set, fingerprint attempts, and third-party requests. See exactly how invasive each site is.
