Is Notefox: websites notes safe?

Low risk

Notefox: websites notes collects page URLs and user interaction events via default-enabled telemetry and syncs them to notefox.eu.

The extension runs a 10-minute telemetry timer that sends page URLs, action names, OS, browser version, and a persistent anonymous UUID to notefox.eu. An optional 'Save page content' feature, when enabled, additionally extracts the full visible text of the active tab and transmits it to the same server alongside the user's notes. Error logs containing the active tab URL are also sent automatically when that setting is enabled.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

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.
