An independent third-party developer implements through the app what should be a settings toggle.
So far, no issues or glitches have been reported.
Thanks to them for that.

Great addon, but it has one major flaw: I want to keep the original subtitles over any generated and over any auto-translated ones. I can only have that with the respective settings turned on, but that also auto-enables subtitles on every video which I do NOT want. I want the translation shenanigans fixed, but the subtitles turned off by default which the addon can't do. If I switch the subtitles options off and then enable subtitles in a video, I get the translated garbage instead... please add a subtitles initial state on/off option as well!

It doesn't stop some titles from being translated, but other than that, it works fine!

Leider ist alles noch verschlimm bessert, diese tool hat mal garnicht geholfen, ich nutze zwar den Waterfox dennoch sollte das genauso funktionieren

It doesn't work with chapter titles, but everything else seems to be working.

Doesn't work for subtitles. YouTube keeps trying to translate to the language of the last video with subtitles.

Works as advertised. A godsend for multilingual users.

Does exactly what it says on the tin. Google, please stop treating us like idiots.
