Appredir URL Blocker

Blocks user-configured URL patterns.

URL Blocker prevents unwanted navigations to user-configured URL patterns. Admins or users can open the extension's configuration page and manage multiple blocked patterns. Key points: - Lightweight and deterministic: browser-managed dynamic declarativeNetRequest rules. - Multiple patterns can be added, edited, enabled, disabled, or deleted from the options page. - No data collection, analytics, or external services. - Runs locally in the browser via Manifest V3 declarative rules. How it works: 1. User installs the extension. 2. The extension opens an options page where blocked URL patterns can be managed. 3. Saved patterns are stored in browser extension storage. 4. The background service worker syncs those patterns into dynamic block rules. 5. Navigation attempts that match a configured pattern are blocked for top-level page loads. Privacy: - No user data is collected or transmitted. - No remote backend is used. - Saved patterns remain in browser-managed extension storage.
