Extension Metadata
About this extension
Numidia Blocker is a privacy-first website blocker that runs entirely on your device. No accounts, no cloud sync, no telemetry — your browsing data never leaves your computer.
🔒 KEY FEATURES
• Domain blocking — Block any website by exact domain or subdomain.
• Pattern blocking — Use flexible patterns (wildcards) to block groups of sites.
• Bulk import — Import large blocklists from local files (hosts files, plain text, etc.) without any remote download.
• Whitelist — Allow specific domains to bypass your blocklists.
• Optional content analysis — Opt-in keyword scanning of page content to block pages matching your own rules (runs locally, never sent anywhere).
• Custom blocked page — Friendly redirect page when a site is blocked.
• One-click toggle — Enable or disable protection instantly from the toolbar popup.
🛡️ PRIVACY BY DESIGN
• 100% local — All blocking decisions happen inside your browser using Manifest V3 declarativeNetRequest.
• No network calls — The extension never contacts any server, including ours.
• No remote code — All logic is shipped in the package and reviewed by Mozilla.
• No telemetry — Zero analytics, zero tracking, zero data collection.
