Extension Screenshot
The "YouTube Control Center" is a lightweight, yet highly efficient extension for Firefox that controls various YouTube playback parameters in order to enhance your experience. The extension has two primary building blocks. First one is the control center panel. When a new YouTube music is streamed, different playback parameters can be controlled right from the panel without the need to switch to the actual YouTube tab. The second part of this extension is the controls that are injected in YouTube pages to change the UI and control volume, quality, and theme of the player.
