Is FuseBase Clarity - Capture Step-by-Step guides, SOP and tutorials safe?

Low risk

FuseBase Clarity lets webpages set the session ID later sent with screenshot and video uploads.

Its content script runs on all HTTP and HTTPS pages and accepts page messages that contain an EverHelperExtMessage session ID, saving that value in extension sync storage. Later Nimbus and Fusebase upload and API requests read the stored value and send it in the EverHelper-Session-ID header when the user captures or uploads screenshots or video.

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.
