I used to use Chrome, but it ate up too much processing speed, so I uninstalled and am now using Firefox. There is a music-related site I'm on all the time, where I can put music files in a Queue and then play them through the browser. This wasn't a problem when I was using Chrome, or IE for that matter, but now that I'm using Firefox and I try the same thing, I get the following message: "Your browser cannot play the iTunes preview file format. Would you like to open the album in iTunes?" NO I DO NOT!!! Why is this happening and what can I do to fix this issue to where I CAN listen to music THROUGH Firefox and WITHOUT having to open iTunes?
