I too have not been able to see the TV lineup since they switched to the improved new line up. I also use FireFox, Windows XP. I called comcast and spoke with someone in cable service who said it was an internet issue and he would transfer me to cable.... He also suggested that I needed to clear my cookies and cashe, which I do after every session. Now if they could get the TV listings to work as well as the constant ad pop ups and surveys that we have to deal with they would maybe have something. All comcast is doing is getting me closer to cutting my cable and placing a dish on the side of my house
