- (2025-06-12) Daniel: Even in passive mode, your extension can only load the original auto-generated subtitle, with no Youtube translation available. Your extension does have a translation function to cover this problem, but you decided to paywall it. Rendering (the current version of) your extension practically useless for most videos. I get that you need to make a living and all that. We all do. But instead of paywalling premium functions (like downloadability, etc), you paywalled a basic function that made your extension useless. What do you think your users are gonna do now? Are they gonna pay you, or are they gonna switch to your competitors? Edit: I saw your post. I don't quite understand what you meant. There maybe problem with Chinese language, but for me (and maybe others too) things have been just fine. The original and the Youtube translation mostly matched each other. There is no major problem. Until now. When both subtitles are integrated in your extension, they physically match each other word by word, making it easy and convenient to read. But now, you know how bad Youtube's own display is. Now it's all over the place. That's why I said your extension is practically useless for most videos. But still, I wanna thank you for posting the needed older version in your post.

- (2024-11-16) Aaron: This is my favorite translation plugin after using many, simple and efficient. The only drawback is that you can't set the color of the original text and the translation separately, if you can set the color separately then it will be great! Would very much like the author to improve and update this feature.

- (2023-12-15) 2In Sub: First off I have to say that I have been using this extension happily for awhile now. I have tried many subtitle extensions and this one, hands down, has been my favourite! Most other subtitle extensions have limited website support and only display bilingual subtitles on the free model. However, the options and features have gradually decreased since I started using the extension. On December 14, 2023, the free model changed to limiting usage to only YouTube, bilingual subtitle display and removing ability to change size of font per language. I am a native speaker of a two languages and used the extension to display at least three languages simultaneously. This method allowed me to understand the nuance of the new language I am learning as I can see translations for the two other languages. Completely understandable that they moved to a pay model, but without previous options, especially multi website / subtitle support, subscription is highly unlikely.

- (2023-07-29) 빈이: This is one of my favorite extensions ever, however recently I'm having problems with youtube subtitles and I tracked it down to this extension. Subtitles keep resetting every other second and flashing on screen as if you had just activated them each time. This happens even with YT's native subtitle system (even auto-generated closed caption) and all extension options off, it only goes away when I disable this extension. I don't use github and don't want to spam the email so I hope this issue gets seen and fixed soon! Thank you for this extension.

- (2023-06-30) Spike Shi: 2020年7月31日 1、建议有一个推荐的默认样式,或者记住上次选择的样式,不然经常要重新设置,很麻烦。 2、与dark reader插件有冲突,开启黑暗模式之后,字幕会一开始很粗大+变黄,然后变成自己调的大小,每翻译一句话就会出现这种情况 ———————— 2023年6月30日 抢钱无疑,这个订阅费用太高了,不掂量掂量自己一下吗?
