Main features

  • Automatically deletes cookies from closed tabs
  • Whitelist/Greylist support for cookies
  • Easily export/import your configurations
  • Clear all cookies for a domain
  • Supports manual mode cleaning from the popup
  • Easily see the number of cookies for a site
  • Support for Container Tabs (Firefox 53+ only)


  1. Add the sites you want to keep cookies for to the whitelist (permanently) or greylist (until browser restart)
  2. Enable "Automatic Cleaning" in settings or "Auto-Clean" in popup
  3. Watch those unused cookies disappear :)


via Official Channels

via Self Installation

Please keep in mind that at this time only Mozilla Firefox and Google Chrome (as well as its development branches e.g. Developer Edition, Canary) will be supported.
Microsoft Edge Chromium will be considered partially official as it is using the same code as Google Chrome for now. While you may be able to install this extension on other browsers (i.e. Varations of Edge, Chrome, Firefox, Android), there will be no official support from the authors and maintainers through Github Discussions and/or Issues.



Donations are done through Liberapay/PayPal. If this webextension has helped you in any way, we would appreciate a small donation to assist in our efforts to make this even better. Note that although Liberapay has recurring donation model, you can opt to 'manually' donate a one time amount as well.

Contributing code

If there are any bugs that only a certain browser has, and you have the fix for it, feel free to submit a PR for it, as long as it does not affect the functionality to other browsers. The easiest is to wrap your bugfix with check for that browser.
