Is tiny_isotope — PaywallUnblock Pro safe?

Clean risk

tiny_isotope reads the active page for a DOI and opens that DOI on the configured paper-search service.

When you click the extension popup, it injects a script into the active HTTPS tab and checks the page URL, metadata, DOM content, and DOI attributes for a scholarly DOI. If it finds one, it opens a new tab to the configured paper-search URL with the DOI appended, defaulting to OA.mg.

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.
