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!

it's works fine in every site videos, I'm use it in coursera👌

I really like this app, but for some reason when I try to translate Russian to English it tells me its waiting on server response or that I'm a guest user and current period quota is used up and it no longer works for me the majority of the time. Please Developer of this extension SEE THIS REVIEW and please fix it. Your app has helped me so much in learning Russian and now I no longer can use it =( I used this extension for so long and to no longer be able to use it sucks, because there is nothing out there like it.

Automatically puts substitles on all my videos + my target language , so good

Good addon
