NoA Blocker by Mochammad Farros Fatchur Roji

NoA Blocker is a strict, performance-optimized content filtering extension designed to block unwanted websites and keywords at the DOM layer before they can fully render.

Key Features:
- Custom Keyword Blocking: Add any keywords you want to aggressively block (e.g., adult content, distractions, specific brands).
- Domain Exclusions: Whitelist trusted domains to ensure false positives don't disrupt your normal browsing.
- Custom Redirects: Automatically route blocked traffic to a safe URL of your choice.
- Friction Lock (Cold Turkey Mode): Secure your settings behind a randomly generated alphanumeric challenge string. Copy/pasting is disabled to prevent quick bypasses, forcing you to manually type the code if you want to change the rules.

Built with lightweight MutationObserver APIs, NoA Blocker stops unwanted content in its tracks without bogging down your browser's performance.
