## Description

**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.

## Review summary

User feedback highlights Cookie AutoDelete as a strong privacy tool that automates cookie cleanup and works well with containers and whitelists, reducing manual cleanup. However, multiple reviews say it no longer works reliably, seems abandoned, and has a confusing, over-engineered UI; non-whitelisted cookies can persist, and some features rely on flags or intrusive container settings. Overall, its privacy benefits are praised when it works, but maintenance and usability concerns dampen its reliability.

### Pros

- Improves privacy by automatically deleting cookies and clearing cache, reducing tracking.
- Automatically deletes cookies from closed tabs and supports whitelists and containers for selective retention.
- Reduces manual cookie cleanup and is easy to manage with clear settings.
- Valued by users as essential for anonymity and greater cookie control.

### Cons

- No longer reliable: cookies are not always deleted as advertised.
- Abandoned/untended project with reports of stale GitHub issues and no support.
- UI is confusing and over-engineered, making setup hard.
- Not reliably purge non-whitelisted cookies; some cookies linger after timeouts or restarts.
- Some features depend on Firefox flags or hard-to-disable container tabs.
