Been looking for an add-on like this for a while. This one works just fine.

Works fine. Sadly no setting options.

its amazing it actually works and its simple and easy to use.. a volume booster is supposed to boost volume and it does just that wow

İyi bir eklenti. sevdim aslında sesi çok çıkmasını sağlaması dahiyane bir fikir aslında

The only volume booster that seems to work. I would suggest they add some kind of way to save the volume on an opened tab. When watching anime I have to reset the volume back up after every episode.
