PROFILE
Ton
Tonnes worked on the thunderbird/thunderbird-l10n repository, focusing on migrating calendar and filter UI localization from DTD to the Fluent system over five months. Using JavaScript, FTL, and front end development skills, Tonnes implemented Dutch localization, improved pluralization rules, and aligned spam terminology for greater consistency. The work included enhancing calendar prompts, context menus, and publishing dialogs, as well as updating filter dialogs for better accessibility and maintainability. By centralizing strings in Fluent and expanding test coverage, Tonnes reduced localization fragility and enabled smoother onboarding, resulting in a more scalable, maintainable, and accessible multilingual user experience for Thunderbird.
