Why would I want this? I watched a translated YouTube video and it was great. If I don't want the translated sound track there's a button right there in settings to change it. Why do I need this extension?
I guess this extension is really aimed at multilingual viewers who don’t want English (or any language they already know) automatically translated into their native tongue. A better solution would be a ‘blacklist’ of languages you understand—so YouTube only auto‑translates from languages you don’t speak, and always leaves familiar languages in their original form.
It‘s even the other way around!
