In June 2025, O. Horvath contributed to the mozilla/gecko-dev repository by enhancing Android testing infrastructure and improving test reliability. Horvath addressed test instability by disabling the Home Screen Jump-Back feature, resolving a persistent bug and ensuring more consistent test outcomes. They expanded test coverage by enabling WebReporter UI tests to run across all build types, not just release builds. Additionally, Horvath streamlined continuous integration by removing obsolete x86 flank configurations and upgrading the Android SDK to version 34 for ARM builds. Their work leveraged Kotlin, Java, and YAML, demonstrating a strong focus on maintainability and robust CI/CD practices.
