That kinda was my prob with firefox. I did their upgarde didnt like it and couldn't get rid of the damn thing. I did a system restore to the day before and it came back, did it again 2 days before and it appeared I got rid of it but when I clicked on ANY desktop short cut, I got the error message couldn't find xp.com WTF was that about , anyway I had to wipe the drive and am starting over . mega PITA........
Firefox lost my vote!!!!!!!!!!!!!!!!!!!!!!
