Unusable as of November 9 update. Only allows YouTube's auto-generated English subtitle as "Original Subtitle" and translation to a handful of languages under "Translation Language". Used to allow your choice of any YouTube auto-generated language in both fields.

This was the best double subtitles extension but now it doesnt work, it shows that there are no subtitles (even though the video has it). please fix it

horrible. cual es el punto de la extension si no soporta japones? es literal el unico idioma (no el unico, pero se me entiende) que usa simbolos totalmente inentendibles para cualquier extrangero, para mi la extension simplemente no cumple si no soporta un idioma tan conocido como este.

Simply good enough.

Works fantastic with Viki! Very nice.

Was the best Dual Subs App, now does not even translate Mandarin, always "Unsupported source language"

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..
