Good

Great add-on.
I just hope to make it fixed for all websites, or at least, for browsing session.

Da kostenlos , super ! Macht was es soll, Danke.

The app really does boost the volume, which I needed, so I'm happy about that. I just wish it would keep the volume the same from site to site. Every time I go to a new channel or website, I have to re-set the volume level. Any way to keep the setting??
Edit 7/28/2022 - What is going on with this app? I have to re-set it at least 50 times a day now. It goes off by itself; it goes off when I change tabs; it does off when I change streaming channels. And I've had a lot of crashes lately - can't totally tie it to this app, but it's suspicious. I keep using because I need the volume boost, but it's getting very annoying.

It has been a great help with listening to videos that have really low volume. Works really well. A big Thank you for making this :)
