Very good application. However, I would like to know if that would be possible having the orthographic correction suggestions that corresponds to the thunderbird settings. I have chosen French for my Thunderbird, but the language is not recognized in the Whatsapp module and the proposed corrections are only in english.

Thanks for the good rating and comment :-) For your question, I am not aware of a way to integrate the Thunderbird spell checker into any website. That's also true for Telegram Web in Thunderbird, GCalTab, and for any website browsed with Open Tab. As an alternative, I use LanguageTool and it rocks ;-)
