What this page can't see
A store listing doesn't show what an extension can access on your computer, and it can't warn you later. Extensions get sold, and the next silent update can change everything.
Extension Guardian watches the extensions you have installed and warns you when one changes owner, gains new permissions or disappears from the store. Free, open source, no account.
