Are traditional characters planned/ being worked on as well? Currently only simplified characters are available in recent stable Firefox. Sites with their language set to zh_TW or zh_HK do not work.
Regarding the Chinese translation, please include Traditional Chinese. If only one version of Chinese can be provided, please replace Simplified Chinese with Traditional Chinese. Traditional Chinese is an important part of Chinese culture. Please do not compromise cultural heritage for the sake of one regime. Thank you very much.
