Does not support the current ESR version 115, which should always be the minimum requirement for add-ons. Now I have to sit and wait for the fix untily July :(

Muy buena, anda de 10!

i used it until 2 months ago. now i can not use it unless i buy windows 10 or high computer.
i will change rating to a 5 star when i can use on win 8.1 computer

I love being able to scroll down and read comments or see what else I can listen to and not miss what I'm watching at the same time. Volume enhancer is a great addition because some videos can be too soft to hear.

ITS BACK!!!! I've been waiting for it to come back! This is a must need extension for youtube! This and UBlock! It allows much more customization and speed when on youtube! If you're thinking of getting it you better hurry! Sometimes it dissapears from the Addons Store!
