Does what it says

works great for setting different volumes on youtube and youtube music.

Works as intended. Doesn't require permissions. Simple and readable code. Deserves 5 stars.

DOES WORK!! - INSTALL

Para youtube esta é de longe a melhor extensão, pois não pede permissões para acessar os dados dos sites visitados. A mais segura que econtrei até agora, é fonte aberto no github.

Good work, and no permissions required.

it worked perfectly for me.

no permissions required, does what it says

A great tool to boost twitter space volume.

This is great! Thank you for sharing :)

works perfectly, simple gui, easy to understand icon, looks somewhat like its part of vanilla firefox when pinned.

It works

simply works, plus no special permissions. would be very appreciated if i could set what volume the 1 to 5 buttons selects.

Отличное расширение, теперь могу регулировать громкость каждой отдельной вкладки. Единственный недостаток этого расширения - его трудно найти.
Автору респект

It just works.

Works perfectly, and it doesn't need any special permissions so no worries about data privacy! Thank you!
