Cookie AutoDelete

Control your cookies! This WebExtension is inspired by Self Destructing Cookies. When a tab closes, any cookies not being used are automatically deleted. Keep the ones you trust (forever/until restart) while deleting the rest. Containers Supported

Cookie AutoDelete is a powerful browser extension designed to enhance your privacy by automatically deleting cookies from tabs once they are closed or discarded. Inspired by Self Destructing Cookies, this extension allows you to whitelist trusted domains, preserving their cookies indefinitely or until the browser restarts. It supports container tabs (Firefox 53+), enabling cookie management across multiple contexts.

Users can easily manage their whitelist and greylist settings, import/export configurations, and manually trigger cookie cleanups from a convenient popup interface. Additional features include the ability to clear all cookies for a specific domain, view the number of cookies per site, and support for local storage cleaning (Firefox 58+). The extension requests necessary permissions thoughtfully and does not modify privacy settings—focusing solely on managing cookies.

To use Cookie AutoDelete, enable the "Auto-clean" feature after setting up your whitelist to watch unwanted cookies vanish automatically, keeping your browser clutter-free and privacy-focused. Comprehensive documentation and troubleshooting guides are available on GitHub to assist users.

No clue how to use this over-engineered extension. The UI is baffling.

No longer works reliably: Some cookies are still deleted, but most remain. Annoying if you rely on this function and end up with your pants down because of it!
