It was pretty good but I seems like it does't work anymore for me. Hopefully it gets fixed.
Un très bon potentiel mais est compliqué à utiliser.
开发者大大，字幕能不能在使用IDM下载视频的时候自动嵌入视频中，这样就不用手动添加在视频中了！
I like this add-ons , but i find there's some problem when i use it. The subtitle shadows sometimes can't align the subtitle . Well this problem happen on my new edge browser . I don't know will this bug will appear in chrome . But i hope Developer can fix this problem.
很好用，但是有一个bug希望修复一下：安装这个插件后，打开B站播放视频会导致视频的菜单选项看不见了，很不方便，必须重新关闭后再打开才能恢复正常
之前扩展的操作比较简单，上手设置一下就可以用了，自从更新之后发现更改不了设置了，就删除了。 后来，在火狐浏览器上使用，发现仍旧是之前的设置，但是当我打开帮助页面查看设置时，发现设置方法已经与旧的版本完全不一样了，这时我才意识到可能是我并未掌握Vivaldi上该扩展的正确使用方法，于是重新安装，打开帮助页面，花了一个半小时按照帮助页面的指导重新设置了一波（主要是细节调试比较费工夫，而个人又比较追求完美），目前用来基本满意（虽然有些小BUG，不过不影响使用就是了），用起来甚至有种成就感。 现在看之前的版本发现旧版本功能确实不够丰富，但胜在简单，新版本功能繁复，设置好了可以非常舒心，但是可能比较耗费时间，个人觉得旧版本更适合普通人，新版本更适合喜欢乱折腾的人，相较之下，个人更喜欢新版本。
Pretty good.
very good, both captions and translations are well synchronized with the videos. Now, the font-size is setted in an absolute way, it's better to set it according to the screen size.
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？
说一下设置字幕时的问题如果一句话比较长，字幕就超出框外了，比较难受。只能把字号调小。什么时候能把一句话设置成长了就双行显示，正常时就一行的呀
