Is Notefox: Websites notes safe?

Low risk

Notefox sends the URL of the page you annotate, with an anonymous ID, to notefox.eu as usage telemetry.

Notefox is a website notes extension. By default, when you use its interface, it records the page URL, browser, OS, language and a persistent anonymous ID, and posts batches of these records to notefox.eu every 10 minutes. Telemetry can be switched off in the extension settings.

Shared hosts - 4 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.
