Is HTML Tag Error Checker safe?

Clean risk

HTML Tag Error Checker sends selected page and link URLs to a local native host during its open-in flow.

When you use its click, browser action, or context-menu flow, the extension passes the chosen page or link URL and tab context to the native host com.add0n.node. The database claim describes this as expected product behavior for opening links through the configured local handler.
