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

Génial, fonctionne du feu de dieu. Un des meilleurs modules FireFox.

I am at a point where I can't use youtube on other browsers because of these missing features. However since the last big update the auto expand feature does not always work, I'd say once every 3 to 4 videos I have to manually expand the video to fit the entire screen. Also, the buttons are transitioning very slowly (3-4 seconds since clicking until something happens), sometimes they stay folded and the three dots do not appear at all until refreshing the page.

Simply THE BEST addon! With the latest version there is no other addon on Internet that can match it (not even close).
