Does not work for all sites.. why does a volume control seemed to be limited for what sites work? It should just boost any volume being played through Firefox.

Second problem is that if you turn it up while video is playing it restarts video at the beginning? WHY? That makes no sense.

Third problem is that for every site you have to re-open because it shows it is at 600% but it's actually not maxed. Open the extension and you will see it has reset itself to 100%

1. Seems to interfere with videos when changing volumes
2. Opening new tab it will still show the 600% but open it and it's actually reset to 100%
3. Being sound control it should work on all sites but it does not
4. No hot keys that I could find to set to max so have to keep opening it and dragging to max for ever new tab.
