ExtRenew por Ant Davis

ExtRenew reviews the permissions your other Firefox extensions hold, in plain English, every 30 days. No account, no server, no network calls of any kind, everything happens locally in your browser.
Every extension gets a plain-language explanation of what it can actually access, plus a quick rating from 🙈 Blindfolded to 👑 Total Control. Renew what you still want, disable what you're unsure about, or remove it outright.

Nothing runs in the background except a once-a-day check for whether your 30-day review is due. No polling, no tracking, no data collection of any kind, "none" is declared explicitly in this add-on's data collection permissions, and it's true.

Already live on the Chrome Web Store, this is the same tool, ported for Firefox.
