Is Privacy Badger safe?

Clean risk

Automatically learns to block hidden trackers while sending privacy preference signals.

This extension sends Global Privacy Control and Do Not Track signals on websites and learns to block trackers that ignore them. It can replace some tracker-based features, such as video players or comment widgets, with click-to-activate placeholders, and it removes outgoing link click tracking on Facebook and Google. Its permissions allow it to work across websites and manage web requests, navigation, tabs, privacy settings, and stored settings.

Shared hosts - 6 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.
