PROFILE
Manuel Bucher
Manuel contributed to mozilla/gecko-dev by implementing privacy-focused cache eviction through the Clear-Site-Data header, enabling precise clearing of bfcache and resource caches such as CSS and images. He expanded Web Platform Test coverage for this directive, updating test infrastructure and refining support scripts to ensure robust validation. Using C++ and JavaScript, Manuel addressed browser compatibility issues in private browsing by disabling problematic shims and improved test reliability by refactoring preference management. He also enhanced documentation accuracy and configuration clarity. His work demonstrated a strong grasp of browser internals, cache management, and web standards, delivering well-tested, maintainable solutions to complex problems.
