Eche Cleaner от Ando

Eche Cleaner is an all-in-one privacy and performance suite for Firefox. It blocks ads and trackers in real time, automatically dismisses cookie banners, and includes a statistics dashboard showing blocked elements per site over time. You can also clean browsing data — cache, cookies, history, and local storage — either manually or on a configurable schedule. A whitelist lets you exclude trusted sites, and the built-in Page X-Ray tool reveals third-party scripts, iframes, and active fingerprinting techniques on any page you visit.
