muy bueno, cumple su función

exactly what I was looking for, does the job perfectly. I wanted to rock to some tunes on YouTube but my headphones are very week for some reason, this fixes the issue!

PERFECT that was 1-2 week i search a solution for that. and there it is, no less, no more , perfect! very thank to you

非常朴实好用的插件，建议加入用户能更改默认设置功能
really nice, but I wish it can add "user can change the default settings" 's feature. It's troublesome to change settings every time

BUG REPORT:
YouTube's playback speed cannot be altered.

Can't increase video speed when using this extension.

Works really well, but does not work with the add-ons "Faster Video" :( if he starts to cooperate, he gets 5/5

Super! Polecam dla każdego, kto chce powiększyć sobie głośność w prosty sposób.

works great, jól működik!

Exactly what i needed. If you hear that is too quiet just , boost the sound in one click.
