Is OpenLink Structured Data Sniffer safe?

Low risk

OpenLink Structured Data Sniffer accepts OIDC auth messages from any origin and stores them in extension storage.

On its OpenLink GitHub callback page, the extension's content script accepts OIDC postMessage payloads without checking the sender's origin. It saves the provided auth payload in extension storage, where later code restores it as OIDC session material.

Shared hosts - 6 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.
