very nice extension

funciona perfecto todo y muy bueno

very good

Excellent extension. Lets me increase the volume of the tab without impacting other tabs. I use in-ear headphones so this is a perfect extension.

Easy to use, does exactly what it says.

Very nice and useful. I like how they've improving it. If only the speaker icon was more visible, because it's grey and since I use FF with dark them, I can barely see it.

Работает! Было бы неплохо, если бы настройка сохранялась не на определенную вкладку, а навсегда :)

Best volume booster, ALWAYS works.

Does exactly what it says. Wish it had a dark backdrop option, but that's the only nitpick I can think of.
