So far it's working well. Some movies and YouTube videos I could barely hear before, are now significantly louder. Also means I no longer have to use a bluetooth speaker.

Works on basically every site that I want such as Netflix, Youtube or paid courses sites. The only issue I have is that it can break fullscreen sometimes, but pressing F11 works just fine

too good i had to come here and rate

Just what i needed. I had an issue with an site that had it's standard volume setting, wayyyyy too low. Even with noise cancelling earphones, hearing anything was a struggle. This addon fixed the problem for me, so thanks to the creator

Nice

Very easy to use and does the job, easy to install as well no problem what so ever.

I really think it is a very useful application, the sound is low in some Netflix scenes. I can increase it with this... There is a problem like this, unfortunately it gives an error at clips.twitch.tv. That's why you're prevented from recording clips.
