Love this addon.

Everything works fine in the new versions for me. Great work!!! And thank you for this excellent extension (Very happy) - donated.

Расширение супер, очень доволен, мне безумно нравится, что здесь есть много гибких настроек на любой вкус:) Спасибо, это реально шедевральное расширение, 5 звёзд заслуженно!

I've already use this extension on Chrome for years.
This add-on provide a lot of features, my best recommend is boost volume. Besides, it also have many great things for you to discover

SUGGESTION: Some videos have terrible audio quality because they play in only ONE HEADPHONE, giving users a headache. If a feature were to be added that changes the sound type from stereo to mono, this extension would be a miracle!

VERY nice

a must have add-on for firefox users

Great addon

feature request: setting that when turned on will skip back a set amount of time when you unpause
