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.

User reviews

Cookie AutoDelete is praised for its configurability and effective cookie deletion upon browser exit, making it a reliable tool for managing cookies over time. However, multiple users report that the extension no longer consistently deletes cookies outside the whitelist after restarting Firefox, even when manually using the clean function, reducing its reliability in recent versions.
Pros
  • Effectively deletes cookies upon quitting the browser.
  • Highly configurable to suit user preferences.
  • Has been reliable over several years according to long-term users.
Cons
  • Fails to delete cookies that are not on the whitelist after Firefox restarts.
  • Manual cleaning (‘clean’ button) does not always remove undesired cookies.
  • No longer works as effectively as it used to for some users.
