Simple answer, No. You'll need to give a lot more information for an
answer. What platform, i.e., 7, XP, 98? How did this start? Internet
Explorer is embedded in newer windows platforms so registry issues come
to mind. If reloading Firefox fixes the problem for that then my guess
is a corrupted registry entry. Move all your files to a safe location as
soon as you can. If you are not the cause of this problem then things
could get worse. It's a good idea to have your personal data in a safe
place when trying fixes. External drives are not that expensive and a
good way to keep backups. Don't touch the registry until you get clear
instructions. Sorry I can't help more.
