I've been a firefox user for a long time, but nothing like this has ever happened. I was listening to music on Playlist.com when all of a sudden (in the middle of a song) the music got really loud and the voice was barely understandable due to echoing and sounding far away. I checked Youtube to see is maybe Playlist was glitching up, but Youtube had the same problem. When I checked the music on the computer, everything was fine. I cleaned up all the cookies, checked all the sound adjusters (everything was fine), and restarted the computer. These didn't work, so I tried turning everything off and waiting. That didn't work either. I went on to Internet Explorer and it was having the same problem. == This happened == Every time Firefox opened == I was listening to my playlist on Playlist.com in the middle of a song.
