Is Netcraft Extension safe?
Netcraft Extension sends each visited site's origin to Netcraft's URL reputation service.
When a tab URL changes, Netcraft Extension reduces the address to the site origin and requests reputation data from mirror2.extension.netcraft.com/check_url/v4/. It uses the result to update the browser action or show a block page for phishing or malicious-script protection.

What this publisher told the store about itself, and the other listings that told it the same thing.
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.

What it can do

Where it sends data
