I use this add-on more than any other.

works great ...very happy with it...no problems at all....recommend it ....

Does it's job well.

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
