The addon works but you have to adjust the volume on every video, it does not keep the settings

This add-on only reduced the sound or returned to sound that is too soft for me to hear comfortably.

I have to give this one star because I have no idea how to use it and there are no instructions here. I'm more than competent with computers and I use Youtube very regularly, but after installing this and restarting Firefox, there's absolutely nothing new on Youtube video pages to interact with to use this addon.

Nice extension... Awesome for sites that play video with low volume. Only thing I would ask is: LET THE SOUND BE MAX FOR ALL SITES... I have to do that every time I open a video page...

Otima extensao para os sites que exibem videos com o som bem baixinho... Ou para pessoas com algum tipo de dificuldade auditiva (tipo eu)... Unica reclamacao: podia permitir que o usuario determinasse o NIVEL PADRAO DE SOM... Eu deixaria sempre no maximo... Atualmente tenho de aumentar o som em toda pagina que tem algum video...

re-sets itself back to zero.

Funktioniert sowohl auf Youtube als auch auf Twitch hervorragend.

works well on the sites it's allowed to except for twitter with mono videos, the mono convert feature doesn't work for me. no sound no matter what.
(i'm using 7.1 surround in windows)

I've been having trouble with YouTube volume ever since I got this new computer, and just installed this add-on, and it's brilliant. I love it so much I created an account soi I could write a review. Thank you so much

It was exactly what I was looking for. But the extension does not activate automatically. It's always disabled, I have to activate it every time I enter firefox... Fix it please...

The sound just disappears completely
