Muy buena, anda de 10!

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!
