Perfect for learning a language where the video has both subtitles. Make sure to go into settings and make the text selectable for even more convenience.

Peut-être que je n'ai pas tout compris mais pour moi il n'y a le choix qu'entre chinois et anglais comme langues traduites, et encore, il faut que la video youtube aie déjà prévu des sous-titres ! Aucun intérêt, donc, j'ai désinstallé...

works perfect now

There is no Turkish subtitle support. Also, when adding dual subtitles, an option can be added for one subtitle to be at the bottom of the video and the other to be at the top.

Yüklediğim tarih iyi itibariyle güzel sorunsuz çalışıyor

It's annoying that the secondary subtitles are always bigger than the original and you can't change it, but it's the best dual subtitles addon for firefox.

Hi dev, Microsoft Edge on Play Store (Android) now offers extensions, would be nice to try the extensions there. Love using this for Scottish Gaelic (Gàidhlig).

Giving 4 star's it's working with youtube.
Please add support for ok.ru..

The latest update has ruined this extension. You can no longer switch styles from the settings and there is no way to toggle the visibility of the subs now. It used to be as simple as turning off captions off, now you have to disable the extension to do this. Used to be my favorite tool. Alas.

Native subtitle no longer works, hope it can be fixed soon, love this extension <3

Good

Works well with mobile youtube. I can translate non english languages to my native language, which somehow even works a lot better than translating to english. And with last update this extension became a lot better as it now remembers language setting (before it had to be manually set every time when changing video). Very good!

Incredibly useful for me learning German!
