Works as advertised, and great for saving bandwidth (i assume, because of reduced bandwidth) for videos on the background, used for music.

To test: once you set it up to change videos to your preferred quality -- try setting a youtube video to different quality, then refresh (quality will auto-change to extension's preference).

It would be easier to use if there was a tool bar button + option to disable video. My use case: attempting to save bandwidth... This extension actually works better for my use case: Audio Only for YouTube™ |
