Best addon to download music from youtube, any other is currently working

Using "Dark" mode, initially, on Waterfox, the icon/image was not visible anywhere but when I enabled previously disabled uBlock Origin on YouTube, a red 3 became visible and I was able to use the plug-in. About 30% of the time, it gives an error and prompt for retry when I do, 90% of the time it works fine so not sure what causes this glitch.

The best

I'm using this addon for years and I find it so useful. I like to listen music in youtube and download the songs that I love. Thanks I love it!!!

Brilliant!

No way to use this, no options appear to do anything.
