Don't work.

Just repeats the songs and doesn't really help with memory or CPU usage.

Doesn't work, you lose bandwith via double video load.

Really poorly written spyware.

Great concept, but unfortunately is non-functional for me; gets stuck in rewind loops and won't play more than a few seconds of audio. Also, this shouldn't need permission for all websites, only youtube.

Not working!

no longer working on youtube or youtube music.

This app doesn't appear under Firefox Addons on Android 9 device. Can download file but this seems to be of no value as it can't open or perform any function.

I can't see the point of using this add-on to stop the video part in the traffic as when I checked the network traffic using DevTools it somehow happens to generate more data compared to the video quality set to 144p
