Technitium-Allow

Adds domains to Technitium DNS Allowed Zones when NXDOMAIN is encountered.

Technitium-Allow is a Chrome extension that detects domains that fail to resolve (NXDOMAIN) and lets you quickly add them to your Technitium DNS Allowed Zones. It keeps a small history of NXDOMAINs and lets you add the current site manually.
