Worked on the duckduckgo/content-scope-scripts repository to enhance user-agent brand handling by removing the dependency on Windows WebView2 within the ua-ch-brands feature. The approach involved a targeted JavaScript code refactor, eliminating WebView2-specific logic, properties, and override options to streamline the codebase. By focusing on core user-agent handling and dropping platform-specific branches, the changes improved maintainability and cross-platform compatibility for front end development. This work reduced the Windows-specific surface area, making the feature more robust and easier to support across environments. The update was implemented entirely in JavaScript, emphasizing clean, maintainable code and thoughtful architectural simplification.
