ShieldBlock - Ad & Tracker Blocker

Blocks video ads, popups, banners, and trackers across all websites using fast Manifest V3 network rules.

ShieldBlock is an ultra-fast, lightweight ad and tracker blocker built for the modern web on Google Chrome's Manifest V3 architecture. ShieldBlock automatically eliminates intrusive video pre-rolls, floating banners, popups, and aggressive telemetry trackers without slowing down your browser. Key Features: - Declarative Net Request Network Engine: Blocks ad and tracker requests at the network level before they load. - Cosmetic Element Hiding: Removes empty ad spaces, sponsored feed widgets, and banner placeholders seamlessly. - Smart Domain Whitelisting: Easily allow ads on your favorite creator sites or trusted websites with a single click. - Real-time Protection Statistics: Live counters showing blocked requests on your active tab and all-time totals. - Custom Rules & CSS Filter Editor: Create custom domain block rules or custom CSS element selectors directly in the options dashboard. - Zero Data Collection: ShieldBlock works entirely offline on your device and never collects, transmits, or sells your browsing data. How to use: 1. Install ShieldBlock from the Chrome Web Store. 2. Browse the web as normal — ads and trackers are blocked automatically. 3. Click the ShieldBlock icon in your toolbar to view live blocked counts, toggle protection, or whitelist the current domain. 4. Click the gear icon to open settings, manage whitelists, or add custom block patterns. Privacy & Security: ShieldBlock runs locally on your machine. All settings, whitelists, and counters are saved in your local browser storage (chrome.storage.local). No external telemetry or network calls are made.
