Is Testofill, Form Filler for Testers safe?

Clean risk

Automatically fills web forms using user-defined rule sets with fixed or random values.

This extension lets users create one or more JSON-based rule sets for filling forms on specific pages, using CSS selectors to choose fields. Forms can be filled automatically or on demand, and rules can also be generated from an already filled form and adjusted later.

Shared hosts - 1 hostname

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.
