这个插件用起来挺直接的，就是在 YouTube 页面上可以一键把视频下载成 MP4，不用再去找那些下载网站或者复制链接。整体操作很简单，基本点一下就能选清晰度然后保存下来。平时想离线观看视频的话会挺方便的，省事省时间。

worked great

Works great, other ones have either broken, or they limit you to 1080p. This one has no limits and even worked without me being signed in!

Works pretty well, so far at least. Out of all the ones I tried this one works the best and easiest.

it works!
