In June 2025, Andrew Churchwell developed two features for mozilla/gecko-dev, focusing on enhancing the new tab page experience. He implemented telemetry instrumentation using JavaScript and YAML to capture detailed user interactions with topsites, such as pinning, unpinning, and editing shortcuts, enabling data-driven insights for future UX improvements. Additionally, he refined the front-end UI with React and CSS by introducing a hover-to-reveal pin icon for pinned topsites, reducing visual clutter while maintaining accessibility. His work demonstrated thoughtful front-end development and cross-team collaboration, delivering both actionable analytics and a cleaner interface without introducing regressions or requiring bug fixes.

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.
