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.

最近Youtube的翻译功能是又抽风了吗，翻译又失效了。 还有是因为服务器费用太贵吗？费用有点过高了

Why is this version of the extension trash compared to the one for firefox? 80% of the settings are removed for no discernible reason

Disney+的<秘密入侵>字幕不同步，之前看其他串流作品沒遇過這種情況，看其他留言下來，好像都是D+會有問題，還請開發者務必修正
