You can easily manage the video with this web tools.

i can watch faster now

Please put an option where you don't affect pitch when you change speed, sometimes i like to listen to song in lower pitch but I can't do it with this addon since it has pitch correction

I always wanted to be able to go faster than 2.0x on videos during the parts I already have seen or know. You can go as fast as you want with this tool. The best

I use it on nearly every website which has videos and it saves me so much time and frustration.

I love it. Helps me save hours and hours of time, works great. I'm so happy to see it for firefox.

It does what it says and it's simple to use. You can change youtube video speed. It's excellent!!!

Отличное расширение! Теперь можно получать больше пользы от просмотра Ютуба.
