Why is it Running?

Reasons it's running:

UI rendering and responsiveness: ddg-browser.exe handles the main user interface and tab rendering, which requires it to stay active to provide snappy interactions.
Privacy protections on loading pages: It enforces tracker blocking and privacy checks on network requests, which can keep the process running in the background.
Extension and settings management: Extensions and user preferences are coordinated through this process and its sub-processes, necessitating ongoing execution.
Background data synchronization: Bookmarks, preferences, and privacy settings may synchronize periodically, sustaining activity in ddg-browser.exe.
Update and security checks: The browser periodically checks for updates and patches, which may trigger activity in this executable.
