Is DuckDuckGo Search & Tracker Protection safe?

Clean risk

Sets DuckDuckGo as the default search and adds tracker, cookie, encryption, and fingerprinting protections while browsing.

This extension changes the default search engine and homepage to DuckDuckGo Search and blocks many third-party trackers before they load. It also blocks many third-party tracking cookies, forces HTTPS on many sites, adds fingerprinting protections, and offers optional Duck.ai and Email Protection features.

Shared hosts - 7 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
