I don't know if it is really 600% I don't really have a way to measure but it 100% works. I have horrible hearing and hate headphones.

excelent add on

I've had some issues with specific sites and this has solved my problem without messing with the audio in other tabs. The only site I've found it doesn't help me with is metastream, but that's more of a them problem than this add-on.

A+

sometimes is very useful

Does what it says in quite a simple manner

works perfectly, dont know why people say it doesnt

does what it's supposed to, unobtrusive

great

I love this extension. However, I do think there could be some minor improvements with regard to having preference options that are able to turn-off the badges as well as make the pop-up disappear once the volume is set. I personally don't need it to stick around once I have selected the volume I want. And I do not need the reminder as to what volume it is set to. Granted, there may be people who want these things and that's why it would be good to have them as options.

This is an amazing addon.i fully approve of this to anyone owning a laptop and stream video image..etc.Where do i donate....thank aliaksandr for an amazing addon.For years the volume was soft on some streaming sites now i actually have to turn down a bit..lol.Great stuff
