🚫 Doesn’t block ads unless they are tracking you

🔍 Algorithmic tracker detection – no human‑curated blocklists

⚡ Lightweight, efficient, and easy to use

🌐 Works with major browsers (Chrome, Firefox, Edge, Opera)

🤝 Open‑source project maintained by the EFF

Perfect for: Users who want to disappear from advertisers’ radar without breaking websites or relying on static blocklists.
