What is ddg-extension.exe?

ddg-extension.exe is the background process for the DuckDuckGo extension. It runs with your browser to enable privacy controls, manage inter-process communication between the extension UI and its background services, and apply tracker blocking and privacy rules. It starts with the browser and typically does not present a user interface.
