i downloaded the Adblock for Mozilla, and it worked good up until about 30 minutes ago. then all of a sudden Mozilla kept having problems and needed to be shut down. it kept doing this. so i deleted adblock, and now i have a problem with about a 3 inch beige banner on the bottom of my screen. i switch over to IE, and i do not have that. i even tried to delete mozilla and try a fresh install. still the same problem. can anyone help me on this?
