The best volume booster add-on. I like it more than any other extension

If you're like me and switched over from Google Chrome looking for an equivalent extension to their Volume Master, this is definitely it. It's just as simple and effective as any native volume controls you'll encounter. Watching a stream and the streamer isn't loud enough for you? Turn it up. And you don't have to be afraid about switching tabs later to YouTube and forgetting that your volume is at 400% deafening yourself, because your YouTube tab will still be at the baseline 100%. It's also great that you can go below 100% as well. I don't know much about the dev, but since I rely on this extension so often, when they asked me for a review of it (which they hadn't pestered me at ALL about in the 7 months I've had it, unlike MANY other devs do for their products) I was more than happy to oblige. Get it and never look back.

Does not work 91.0 (64-bit)

good

Works great! thanks so much. Watching videos is now clearer with this extension. thanks again!

can fullscreen without f11, really nice

It's a really good addon, i'm happy !

its really good! i totally recommend it, you can download with no worries cause it is going to work beautifully

My goto app for volume boost. Special on YouTube, after recent YT video changes, many videos have low volume audio, this fixes that. Works on all websites.

Good , if full fledged stereo output is incorporated, will make this add on an top performer

Es excellente... permite subir mas el nivel de volumen de muchas paginas y no distorsiona

Не работает(((((((
