I looked into this, but Firefox’s extension API does not provide reliable site-specific cache clearing. The UI and site list management are doable, but the core promise of “clear cache for one site only” is not. Firefox only supports hostname-scoped removal for site data such as cookies, IndexedDB, localStorage, and service workers, while browser cache clearing remains global. Because of that, implementing this feature as described would be misleading: it could clear more than the selected site or behave inconsistently depending on the data type.
