There is no Chinese translation support, which is the most unfortunate point.

Regarding localized translations, my personal opinion is that Firefox can appropriately give up its support for perfect privacy protection in the area of web page translations. Users like me may not care that the translation engine knows what they are browsing, as long as Firefox can ensure that the captured content is only used for translating and improving translations.

It might be useful to ask for permission to remotely transfer web content in order to support more languages. For users who do not agree, the current localized translations will continue to be used.
