It does not work. Simply put.

isn't doing what is supposed to be doing

It doesn't work.

Yet another Audio only add-on that does nothing...

doesn't work

I just gave this add-on a try, but it didn't work. When I enabled it and clicked to play a YT video, I got the following error message: An error occurred. Please try again later. (Playback ID: 1STozZPhhspvh7MN)

Doesn't work. Gives me a video error message.

Useless and causes every video to fail to play

无法使用。点击图标后刷新网页，但是本扩展没有启用，还是灰色图标，而且视频画面还在显示，无任何作用。

Stream dose not load or often reload and become can't hear sound.
But same extention works fine at Edge.

Seems to indeed not load the video. However as stated in latest comments, refreshes the videos after a few minutes, so useless as of now.

It doesn't work anymore.
