very ok - don't know if the add-on remembers a site or if it's possible - but very well already

Great Extension. If you could add global boost feature, to enable me to boost volume for all open tabs.

Only one that works. Just install!

Does its job. Lots of keyboard shortcuts.

Works well, but for some reason when installed (even disabled) it causes the chat window on twitch.tv to disappear every time you resize/clip the window in Windows 10. Inconvenient enough for me to uninstall.

Отличное расширение браузера! Советую))

intuitive
functions as intended
awesome add-on

Твой поцелуй
Асия, NЮ

Does exactly what it says it will do and works very well. To get 5 stars though, it would need to remember the volume it was set at.
