This extension automatically clears site data (cookies, local storage, indexedDB, etc.) for a website after you close its last tab. It waits for a short delay (configurable) before clearing the data.

Its primary feature is full support for Firefox Android and Firefox Containers. This allows you to maintain separate exemption lists for each container (e.g., keep google.com logged in for "Work" but clear it for "Personal").
