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

This add-on is a must have for me. Many YouTube videos have a very low volume and with "600% Sound Volume" I can listen to them.

I really like the addon, it does exactly what I want it to do... I have to turn it off to play tiktok videos in FF though. Not a big problem, but if that could be fixed that would be nice

Works very well on my laptop, which has not so good sounds, making online movies hard to hear. This booster tremendously helps w/the sounds.

Please fix the dark theme icon (it's black just like light theme's)
