Literally works, and even better you can go lower than 100%

Brilliant extension i use across all my devices. Gets the job done on most of the websites.

great add-on, does exactly what it promises, I use it all the time and never had any issues with it.

Normally this works perfectly fine but I'm running into a problem at the moment.. it isn't working for a YouTube video. No idea why!

When it works, amazing ad on but when it doesn't it's just super frustrating.

Great extension! The only suggestion I have is to make a light-colored version for dark themes.

Good. Thanks all!

Technically works, but isn't as functional as I hoped. It does its job well enough on Youtube, setting the volume to 0% mutes it, and 600% boosts it louder than I believe is normal, though I'm unsure it's "600%".

This wasn't my issue though, my problem is that it doesn't function AT ALL with Spotify, a popular music listening platform. Setting it to mute or to boost doesn't effect the volume at all in any way. I hoped it would be able to work on any site but I guess not, would be neat to see this fixed.

Love it! However, it breaks Twitch clips AND more notably, the playback speed functionality (in all web players I've encountered so far). It would be nice if I could fix the low volume some lectures offer AND be able to speed them up at the same time :)

It controls your entire Tab volume once you turn it back to 100%

Thank you Aliaksandr, now I can hear my television shows with my broken headphones! :)

Only a 4, but would be a 5 if it didn't break Twitch clips. I get this error whenever I try to use it on clips that are too low to hear: This video is either unavailable or not supported in this browser. (Error #4000)

I hope there is a fix for it soon.

Simple and effective.

I have finally found a youtube audio booster, this extension is a blessing for playing low volume video.

even works on sites where sound-fixer doesnt, like some sites where you can watch movies
