it works great

Pretty good with plenty of options for customisation, definatley recommneded.

this is epic! i love it sooooo much :) the pop up video when you scroll down, speed control, and wheel scroll volume control are amazing. i literally install this on every firefox i use soon as i install firefox. i have many computers and do pc repair so i install firefox quite a bit. thank you!

WONDERFULL!!

Really useful add- on, thank you.

The best add-on for Youtube that I've found. Changed my entire YT experience & now I cannot live without it!

So you know how when you set up a new PC PC there are certain things that just have to go in right away. Things like malwarebytes, and Firefox, well this is just one of those things. For years I used a few different extensions to get roughly the same effect , but this brings everything together in one extension and honestly handles everything better then my old extensions ever did.

Highly recommend giving this a try

I love it

Handy - you can turn up/down the volume with mouse scroll and continue to watch while browsing the comments.

Excelente extensión.

Really great features!

perfect Add-on and does what it says perfectly!

Wow, just... wow! Awesome experience. And I have successfully hide recommended videos by Custom script. Thank you for this wonderful add-on.

The best, well after the YouTube app anyway, close to best without getting burned.

Excellent add-on that allows me to scroll down and do other things while watching the video!
