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

It works

Functional, but when trying to lower volume it doesn't allow volume to go below what it was set at. Tried Youtube Music, and Youtube.

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

Does absolutely nothing.

Doesn't work. Tested on Google Meet.

It just works.

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

simply it does everything right
