Is Signer.Digital Digital Signature, PKI safe?
Signer.Digital Digital Signature, PKI lets any webpage send PKI action requests to its native host.
Its content script runs on every web page and accepts same-window postMessage objects that only need src: "user_page.js". Those messages are forwarded unchanged through the background script to the Signer.Digital native host, which exposes certificate selection, signing, decryption, smart-card, and certificate import actions.

Shared hosts - 3 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.
