Ad Blocking Is
Just the Beginning.
Your Browser Needs More.

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.

Ad blockers stop ads. What stops everything else?

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.

Cookie Consent Banners

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.

Browser Fingerprinting

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.

Phishing & Scam Sites

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.

Data Breach Exposure

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.

Tracking Link Parameters

URLs are loaded with fbclid, utm_*, gclid, and dozens more tracking params. PII Fortress strips them automatically on every navigation.

Prompt Injection Attacks

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.

An honest, feature-by-feature look

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.

Works alongside your ad blocker

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.

DNR Rulesets Merge

Chrome's MV3 architecture allows multiple extensions to register declarativeNetRequest rules. Our 170,208 rules and uBOL's rules coexist without overriding each other.

No Overlap, No Conflict

uBOL handles ad blocking. PII Fortress handles cookie consent, fingerprinting, breach monitoring, scam detection, and everything else. Different responsibilities, zero duplication issues.

Same Filter Lists, Different Goals

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.

Features no ad blocker offers

These capabilities exist in PII Fortress alone — not in uBlock Origin Lite, not in Ghostery, not in any other single extension.
