This guide was written by a Vietnamese Firefox user with nickname @ndv92, this is the original post: https://voz.vn/t/tong-hop-nhung-addon-chat-cho-firefox-pc-mobile.682181/post-27739740

This Vietnamese thread is surprisingly deep about Firefox, but there's a lot of slangs so Google Translate won't make it.

None was written by me, I just translate it to English, literally.

Thanks for reading, And thank @yokoffing for making and maintaining Betterfox.
