c'est clairement l'extension ou on trouve le plus de traduction française (surtout pour prime et netflix), vous pouvez gérer les sous-titre comme vous voulez.
work as expected, but why need my web history for what
The extension is brilliant, but I have one question. It seems that when I use the built in subtitle searcher, none of them work. Please fix this bug. Thank you. This extension doesn't seem to work on Mozilla Firefox. It does not detect the HTML5 video. If this could be fixed, that'd be wonderful. It works well for Google Chrome though.

I tried many different subtitle extensions and this is the only one I leave installed and enabled. I don't use it very often, anymore, but it's really useful when I need it.
Great extension but could u please add language learning features to it, AI auto subs & translations etc too. or make a advanced version of it that supports this all.
The greatest extinction that I ever seen, It's really useful.
I recently installed your extension. I'm finding that the extension works well for most languages, but I'm experiencing some issues with Arabic subtitles. Specifically, when the subtitles contain punctuation such as "..." or "?!", the text being with punctuation Instead of ending with it. I was wondering if you could look into this issue and see if it's possible to fix it. It would be great if the extension could fully support Arabic script and properly render the text direction for Arabic subtitles. Thank you.
To the creators of this application, thank you. Please, please, please ensure that this application will run and be in working condition for the next 100 years and longer, because it provides a fricking brilliantly amazingly good feature! You guys don't know how much this means to us! It does what Substital does, but doesn't replace the video feature. Please consistently be active and know that we, the users, are very grateful for what y'all do! :)
I have been using this extension for 5 months now. While there are other extensions available, those completely replace the video player on the website, which is why I only use this one. I mostly use my Mac to watch videos, but sometimes I also use my mobile. Previously, in December, I reported some problems for mobile devices. You have done a great job in addressing those issues and making the extension responsive for mobile devices. However, one thing that still needs fixing is that when we rotate our mobile, the subtitles do not show up. I understand that you are very busy with other projects, but I would be very thankful if you could fix this one issue. I really appreciate your hard work.
