About this extension
CAD Neo is a community-maintained fork of
Cookie AutoDelete.
Cookie AutoDelete has not had a release since v3.8.2 (December 2022).
Since then the upstream project has only seen dependency and CI updates, and
long-standing pull requests — including full Firefox for Android support —
have not been merged or shipped.
As a result, on Firefox for Android the upstream extension cleans cookies
but silently leaves other site data behind: LocalStorage, IndexedDB, the
cache and Service Workers. That is easy to miss and defeats the point of the
extension on mobile.
All original work is by the Cookie AutoDelete team. Android site-data support
is based on upstream PR
#1803 by

This fork is not affiliated with the original authors; it exists to keep the
extension working, especially on Android.

- Full site-data cleanup on Firefox for Android: the LocalStorage,
IndexedDB, cache, plugin and Service Worker cleanup options are now available
in Settings (and per expression) and actually run, instead of being hidden and
skipped. Requires Firefox for Android 85+. - Keeps the classic Cookie AutoDelete behaviour on desktop.
- Focused, small changes on top of upstream — no unrelated rewrites.
- Deletes cookies from tabs you close, while keeping the sites you trust
(whitelist / expressions). - Optionally clears LocalStorage, IndexedDB, cache and Service Workers.
- Containers, cleanup log, manual cleaning, import/export of settings.
