Web Block

Web Block is a minimal, privacy-first Firefox extension designed to help control distraction and reduce addiction by blocking specific websites or sections of websites.

Instead of blocking entire domains, Web Block allows path-level blocking, so you can block only the distracting parts (like YouTube Shorts) while keeping the rest of the site usable.

Features

• Block specific site sections (path-based blocking)
  • Example: youtube.com/shorts
• Works with modern SPA websites (YouTube, Instagram, Twitter, etc.)
• Keyboard-first, minimal popup UI
• Add rules by pressing Enter
• View blocked sections in a dropdown list
• Delete rules using Backspace / Delete
• Dark mode (persistent)
• Local-only storage (no tracking, no analytics)
• Lightweight and fast

Privacy

Web Block does not:

• Collect any personal data
• Track browsing activity
• Send data to any external servers

All rules are stored locally using Firefox’s extension storage.

How It Works

• The extension listens for page navigations and URL changes.
• If the current URL matches a blocked rule (host + path), the page is redirected to a local blocked screen.
• SPA route changes are handled correctly.
• A safe “Go back” option returns the user to the last allowed page.
