- Network-Level Blocking: Uses Declarative Net Request API to block cookie consent scripts before they load
- Automatic Banner Removal: Intelligently detects and removes cookie consent popups via DOM manipulation
- Tracker Blocking: Blocks known tracking scripts and cookies
- Customizable Settings: Fine-tune blocking behavior through the extension popup and options page
- Lightweight & Fast: Optimized build with minified assets and efficient rule matching
- Open Source: Fully transparent and community-driven
Cookie Blocker operates on multiple levels to ensure cookie banners are effectively blocked:
- Declarative Net Request Rules (
rules.json): Blocks known cookie consent scripts and styles at the network level before they execute - Content Scripts: Injected scripts that handle remaining cookie banners through:
- DOM manipulation and element hiding
- Automatic "Accept" button clicking
- Storage cleanup (cookies, localStorage, sessionStorage)
- Popup UI: Quick-access controls to enable/disable blocking and adjust settings
- Options Page: Detailed configuration for advanced users
