Avaliado em 5 de 5 estrelas

I did not test it actually, but I give 5 stars just because somebody made it possible. For a long time I was missing such a feature, silently hoping that someone will develop an addon like this. So it is'nt really important that there are missing sounds. This addon will help both, developers and users. It is an important step towards a better Firefox.
Thank you.
