DoubleSubs

bad optimization on video playback like netflix

Has potential but it does not seem to work with French. It started in Russian and English and both worked but for some reason it won't allow French to show up in the subtitles. It even works with English and English in double subs. It also has this issue common with double sub extensions where the subtitles move when you hover over a video and with constant pausing that gets annoying with these extensions.

Hi. I've just checked and French language works correctly. You need to choose it in settings https://app.doublesubs.com/settings/general and then refresh the YouTube page.

Oh it's very good, thanks you very muchh and the most special thing is that it's free

Works great with Youtube, but currently not on Netflix

After the update everything got worse. Namely: No translation in the text, no double subtitles on YouTube, no button to save to dictionary. How to use it now?) But there are cards for training, this is super, thank you. I am not lowering the rating, please fix it! I tested this in two different browsers

Thanks for your feedback! YouTube dual subtitles should be availabele right now. Try to select "Dual subtiles" on YouTbe. In v3.0, text translation and the “Save to Dictionary” button are temporarily unavailable. I plan to add most of missing these features within about two months.

Thanks for the feedback! Netflix recently released an update that broke some functionality in the extension. I’m already working on a fix and will release an update soon. I’d really appreciate it if you could consider updating your rating after that :)
