Make your home page compatible with IE. I will not upgrade to Firefox. Now I have a reason why I will not to use Yahoo.
Why do you keep changing your home page. Apparently your web development team does not have the expertise to make a decent web page that is compatible to IE. Therefore, I will not change to Firefox so it is good bye to Yahoo. Yahoo was good until you came up with the idea to have all IE users convert. Dumb Idea
