Auto Reject Cookies is a Firefox extension designed to streamline the cookie consent process by automatically rejecting cookie banners across various websites. This tool supports over 25 Consent Management Platforms, including popular ones like OneTrust and CookieBot, and recognizes reject buttons in multiple languages. It effectively handles complex banners that hide the reject option and prioritizes rejecting all cookies over individual selections. Additionally, it sends Global Privacy Control signals for compliance with privacy regulations, ensuring users can opt-out of data collection legally.

This extension emphasizes user control and privacy, allowing users to toggle its functionality with a single click and whitelist specific sites if desired. It does not collect any user data, operates entirely locally, and is open-source, making it transparent and auditable. The user interface features a visual indicator for successful rejections and provides statistics on rejected banners, enhancing the overall user experience.
