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 :)

Thank you!! YouTube is always too quiet without this addon...

1. The tool is extremely straightforward and simple to use.
2. It does exactly as it said, just pump the volume boost as much as you need and those videos you really want to watch without headphones but are low on volume, suddenly become loud enough that you can double task or w.e it is you were planning that required a boost.

Мучаюсь с эти приложением. Нужную громкость звука приходится устанавливать при каждом входе на страницу по несколько раз за день. Это откровенно раздражает. Будет лучше, если уровень звука будет фиксироваться сразу на 600%, для всех приложений и сайтов.

The volume boost itself works well. My two issues are that it can need re-setting for each new video (the number stops representing the actual volume after the first video), and that the hotkey to bring it up cannot be rebound. I have something else set to shift+ctrl+v.

Used for Lenovo Y520 with low volume issues. This app work well. Thank you.

brilliant addition to firefox

Does what it says and does it well. However, one does need to have the audio playing in order to change the volume. It would be better if one could change it wasn't playing.
