In June 2025, Andrew Churchwell developed two features for mozilla/gecko-dev focused on enhancing the new tab page experience. He implemented telemetry to capture detailed user interactions with topsites, such as pinning, unpinning, and editing shortcuts, enabling data-driven insights for future UX improvements. Using JavaScript, React, and CSS, Andrew also refined the UI by introducing a hover-to-reveal pin icon for pinned topsites, reducing visual clutter while maintaining accessibility. His work demonstrated a thoughtful approach to both analytics instrumentation and user interface design, with robust code changes reviewed across teams, reflecting a solid understanding of front-end development and telemetry integration.
June 2025 monthly summary: Delivered analytics-enabled Topsites Interactions Telemetry and a UI refinement to reduce clutter on the new tab page. The telemetry captures pin/unpin actions and shortcuts add/edit interactions, enabling data-driven product decisions for user engagement with topsites. The UI change (hover-to-reveal pin icon for pinned topsites) declutters the page while preserving quick access to important shortcuts. These changes were implemented in mozilla/gecko-dev and landed alongside related bug work, supported by cross-team reviews and robust code changes.
