Is Nervenschoner safe?

Clean risk

Nervenschoner checks browser requests against local and auto-updated filter lists to block or redirect matching URLs.

Nervenschoner uses broad webRequest permissions to inspect navigation and resource URLs as pages load. It applies bundled and downloaded filter lists, including its own Nervenschoner list, to decide whether to allow, block, or redirect requests. The reviewed code shows these checks happening inside the extension rather than forwarding visited URLs to a remote service.

Shared hosts - 5 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.
