Super! YT playback rate shifted at the touch of the shift key and the mouse wheel!

it is great

Works very well. Simple and to the point.
Perfect solution after the Enhancer for YouTube™ got pulled from Firefox by the author.

This extension is really well made and works as promised. Love it.

Simple and effective. Allows you to increase the speed beyond the max x2 allowed by YouTube. Works really well, thank you to the add-on creator for making this.

Minimal & convenient

Funciona bien, exactamente igual que en Chrome. Siempre pongo ocultar siempre el panel y uso las teclas + y - del teclado para regular la velocidad. No entiendo por qué tiene tantas notas negativas.

Лучшие! Спасибо огромное за Ваше старания.

Works well and is easy to set up.

Really convenient...
