This extension adds the following functionality to youtube.com and m.youtube.com:

• Works on Desktop and Mobile.
• Works with the regular video player and the mini-player.
• Save battery and bandwidth.
• On desktop use the toggle in the lower right corner of the video player to enable audio-only playback.
• On mobile use the semi-transparent floating button on the lower left part of the screen to enable audio-only playback, you can also "leave" the page and playback should continue normally.
• Seamlessly switch between audio-only and video playback using the toggle on desktop or button on mobile.

Limitations:

• Doesn't work with live content.
• If autoplay is not enabled there may be some strange behavior.
• Depending on your network connection on some rare cases it may take a couple of seconds to get the audio-only stream, until it does it may render the video first but just for a brief moment.

Works best alongside an adblocker like ublock Origin.
