On this site http://www.top40.nl/ i can click on examples of the music so i can hear what the song is. But when i click on a song there is nothing played. My hardware is a acer laptop with x64 windows 7 home premium. I have installed flash but nothing help. On internet explorer this website plays sound without problems. I have no firefox addons installed except for adobe flash. i dont no what this is. Also why there is no x64 version of this browser???? fLASH SUCKS on firefox. I have delete this crap browser from my laptop. This browser can not play music files on internet. internet explorer is 64 bit and can play music files simple without any problem so the problem is firefox.
