Very good

this the Best themed Youtube out there with amazing you tube Modification available

An absolutely brilliant extension. Will do everything you've always dreamed of and even more.

Has always worked as promised, plus regular updates. Thanks!

I use this app all the time. I love being able to speed up videos because, let's face it. Some people talk too damn slow! It's also great when I'm looking for something particular in a vid so I can get past what I don't need to watch and find what I do. I wish I could use this app with netflix and hbo.

And ya gotta love the audio enhancer. You know when you're watching a vid and you just can't hear it even tho you've got the volume cranked? I just put my cursor on the vid screen and brush up on the track pad and it pushes the audio higher than what my laptop was allowing. I.LOVE.that! OH! And the best part is that it skips ads! If you like to watch stuff while you're working on other things, the fact you don't have to stop to skip ads is fantastic. I LOVE that TOO! You should definitely try this app. And if you love it and use it as much as I do, thank the developer and toss em a fiver. It's totally worth it! I did!
Thank you Developer Guy!
