What is ddg-browser-helper.exe?
ddg-browser-helper.exe is the auxiliary Windows process used by the DuckDuckGo Privacy Essentials extension. It runs locally to support tracker blocking, privacy lists, and secure handling of extension-driven tasks within Chromium-based browsers.
The helper communicates with the browser extension over a local channel, applying privacy rules, updating blocklists, and coordinating background tasks without exposing user data beyond the browser.
Quick Fact: The ddg-browser-helper.exe process is designed to operate only when the DuckDuckGo extension is active, reducing idle resource use when not needed.
