Is Bookmarker by start.me safe?

Low risk

Bookmarker by start.me accepts external messages that can navigate the active tab or open caller-provided URLs.

The extension exposes an external messaging handler that accepts messages from other extensions and selected web pages without sender validation. Those messages can tell it to open a new tab or navigate the active tab to a supplied URL; the available evidence does not show user data being sent to a named recipient.

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

Shared hosts - 2 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.
