Is Dark Mode for YouTube™ safe?

Low risk

Dark Mode for YouTube™ exposes its extension ID and resource base URL to YouTube page scripts.

Dark Mode for YouTube™ adds a hidden marker to YouTube pages that contains the extension's runtime ID and internal resource base URL. Scripts running on those YouTube pages can read those values, but the confirmed claim does not show them being sent to an outside service.

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.
