Does what it says on the tin. I've not encountered any problems using it over the span of a couple of years.

Great little app for the hard of hearing like me! One click and your done. Does not distort the sound, which is a big plus, I use it for Firefox and have had no issues with it, so if you need an app to boost the sound this is a great choice.

Made an account just to review this add-on, its very good.

this is what i wanted

ottimo !
funziona son tutto

Does exactly what it is supposed to do. 5 stars because of that.

Great

Doesn't work with soundcloud

Breaks Twitch clipping feature, cannot clip, issue reported over 3 years ago still not fixed. The 'error #4000' thing. Reported on r/firefox and only solution is to disable this addon.
