Is Ful.io - Technology Profiler and lookup safe?
Ful.io sends the active tab's hostname to api.ful.io when you open the extension popup.
When the popup loads, it reads the active tab URL, extracts the hostname, and posts it as JSON to Ful.io's lookup API. The manifest only grants activeTab and the code performs this lookup from the popup, so the evidenced behavior is tied to opening the extension rather than automatic page monitoring.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 3 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.
