PROFILE
Manuel Bucher
Worked on the mozilla/gecko-dev repository to enhance browser privacy and reliability, focusing on cache management and private browsing compatibility. Developed Clear-Site-Data header handling to evict backward-forward cache and clear CSS and image caches, iterating through browsing contexts and session history for thorough cache eviction. Expanded Web Platform Test coverage for cache directives, updating test infrastructure and support scripts. Addressed documentation accuracy and configuration clarity, including corrections to tracking protection links and data sanitization references. Improved test stability by refactoring preference management in JavaScript-based tests. Utilized C++, JavaScript, and Python to deliver robust, privacy-focused browser features and maintainable code.
