Just works, and the most recent update added an aesthetically pleasing UI enhancement that's really easy to personalize. There's a good reason it's on Firefox's Recommended list.

Been absolutely smashing it with this recent update! This extension in general is a severe improvement of my youtube experience. I could probably not live without this extension anymore. Just donated as well!

I've been using this for a looong time and I really love this a lot. When i listen to music my volume is low but with this i can force it to be louder and its helpful. With the new looks and customization, I feel like I have even more control. My favorite look is the Ubuntu Purple and the others are very well done too, lot's of options to choose from and given the option to make our own theme is awesomeee. Great Job!
Edit: I just noticed the video filters, I love the idea of it a lot because that could help out a lot of people with vision problems and so on.- thanksss

Love the new update, can pick the good part of the song to listen to without all of the rest.

Great add-on. Only thing annoying me with the new update is the Auto-play feature is constantly being reactivated.

incredible and usefull work thankyou!

Such a great app, honestly the only thing I want is continued development!

Nice One!
