A extensão é MUITO boa, pena que não funciona em alguns sites como por exemplo no whatsapp web

Its super buggy and many times it doesnt work, but im giving it 4 stars because it is the only extension that I found that let you choose the volume for each site you visit and remember that preference.

Works as advertised for me in FF 87.0 x64. Only criticism is that AVG regularly alerts me that this extension is badly rated for performance hits and wants me to remove it. I have seen no sign of resource hit by this add-on, but something about it peeves AVG anyway, FWIW.

I came in peace, for all Mankind.

This is a wonderful addon that I didn't know I needed. I was looking for an addon to easliy lower FF's volume and found that a per-site volume is even better. Edit: doesn't seem to be persistent on Reddit (changing the volume in Reddit's video player changes the maximum website volume in the addon)

Great module ! I just wish we could make a boost ( > 100%) for some very soft sites. Could you allow a 0-200% volume slider for example ? By the way, I do not understand how the "max volume" slider affect the sound... (what is the difference with the lower volume slider ?)
