this is just what I need to hear lots of videos online. thank you.

I find no advantage to the extension...after downloading...no change in volume increase ability.
So...what am I doing wrong that I find no advantage?

It's good, I just want a way to have it persist in websites of my choosing. For example on youtube I always want it to be at 300-400% but I have to re-do it every time I reload or open a new video. Please add this feature if you can

nice

Perfect!! It works flawlessly.

Свою задачу выполняет. Поставил, чтобы увеличить звук на ютубе. Простое управление.

Штука хорошая, но раз в пару минут происходит какой-то бешеный бросок громкости с перегрузом.

An excellent audio control using Firefox while on a Mac computer.

Addon is broken on many sites due to CORS violation, e.g. on Bandcamp site.

I can finally blast DnB home alone.

I really like it. It works quite well.

It works. I´m content.

This app does its job well, by adding it to another volume control, myself being partially deaf can hear and enjoy, thank you all, you have made an old man happy.

doesnt work
