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.

works perfect now

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).

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!
