Так то полезный аддон, но Stop Autoplay очень криво работает, открываешь несколько страниц ютуба, ставит на паузу, переходишь на какую нибудь, нажимаешь воспроизведение... а через секунд 3 опять ставит на паузу...
Этот аддон идеально ставит на паузы...

The best extension for Firefox. You can change the speed of the video for any value you want, like 0.9 1.2 1.3 and even beyond the limit, going to 2.2 2.5
That's my favorite feature.

After the new Firefox v81 update, the plugin doesn't work as before. The videos need to be clicked twice to be played, the cards at the end of videos are not hidden anymore and so on. Please update this if possible, it's a very good plugin for Youtube. Thanks!

I simply would not be using Youtube at all without this App. Tanks guys

Fantastic extension that automates so many settings and makes my YouTube Premium experience even more premium. Be it actively watching videos or playing music in the background while working or driving, I cannot imagine getting a good experience without this addon. Thanks to the kind folks behind it. Yes, there may be some bugs but this add-on deserves 5 stars.
