Has a rather limited Range. I use it to have a tab play music very quietly in the background, and with the lowest sound setting on obth YT and this Addon it just about works more or less but i whish i could make it a little more quiet. A positive: the setting gets saved between different browser sessions.

It works, just don't max it will destroy your sound system if you have a cheap one.

does not wok in all sites. but ok. so far only https://archive.org/ will not boost, have to refresh site and play normally.

Utilizo bastante nos vídeos!! Muito bom!! Super recomendo!! Parabéns ao(s) desenvedor(es)!!

Best sound booster ever!

It does what it promises, it increases the tab volume. I would only ask an option to increase volume on all tabs, also, when I move the slider there's a one second silent pause, I'd like it to be more fluid, without that pause.

late bloomer here . but this app make me look like i know more than i do. thanks love it..

It's very helpful really but sadly it doesn't work well with video speed :( You can only play at 1x speed if the volume booster is on

Палочка-выручалочка! Огромное спасибо за это бесплатное дополнение, теперь я могу управлять звуком как считаю нужным. Если тихо - это дополнение, большие скачки по громкости - Sound Locker. Удачи вам, разработчики!

Works as advertised. I especially like how I can click the extension and use arrow left/right to adjust by 10% at a time

works like a charm

Muy util, te pido que revisen que no se puede incrementar el Volumen y aumentar la velocidad de los videos de youtube, si lo pones a velocidad 1,5 x o 2 x no le aumenta la velocidad al video
