uBlock Origin Lite is one of the best ad blockers available, trusted by over 16 million users. PII Fortress uses the same filter lists and adds 10+ privacy and security features that uBOL was never designed to provide. They work well together.
This is not an "us vs them" comparison. uBlock Origin Lite is excellent at what it does. PII Fortress extends your protection into areas uBOL does not cover — consent management, fingerprint shielding, breach monitoring, and more. For maximum browser privacy, use both.
Both extensions compile the same community-maintained filter lists into Chrome's Declarative Net Request (DNR) format. This is the same battle-tested blocking engine that powers effective ad and tracker removal across millions of browsers.
uBOL focuses purely on content blocking. PII Fortress covers the full privacy surface.

uBlock Origin Lite and PII Fortress are designed for different purposes and run without conflict. Here is what each handles when both are installed:
Where blocking rules overlap (both use EasyList/EasyPrivacy), Chrome's DNR engine deduplicates automatically. There is no performance penalty and no rule conflicts. Each extension handles its own unique capabilities independently.
Additional capabilities currently in development:
iOS support available via Microsoft Edge (ad blocking, cookie consent, link cleaning). Safari Web Extension on the horizon. Android supported via Edge and Brave.
On-device ML models to identify emerging threats, zero-day phishing patterns, and suspicious page behavior in real time.
Encrypted sync of your privacy preferences, whitelists, and settings across all your browsers and devices.
Built-in VPN toggle with a no-log provider, combining network-level and browser-level privacy in one interface.
Keep uBOL for what it does best. Add PII Fortress for everything it does not cover. Guard is free forever.
