Excellent and very practical extension.
YouTube Audio Mode solves a real problem for anyone who wants to listen without wasting bandwidth on video. Audio-only mode works with one click, and the extension automatically lowers video quality without affecting audio playback.

What I liked:

Significant data savings.

Clean, modern UI with a pleasant visualizer.

Clear statistics showing saved bandwidth and listening time.

Smooth integration with YouTube, no interruptions or reloads.

The extension is lightweight, privacy-respecting, and requires minimal permissions. Perfect for Quran, lectures, and podcasts
