I will have to think about this some more. BrainKing should not know or care what browser a user is using - and would either think Firefox is messed up for all sites you visit, or BrainKing is messed up for all browsers you use.
OR one other thing I thought about while I was trying this, go to Tools, Options - and the "Content" area.
To the right of "load Images", choose "Exceptions"
If Brainking is listed there, choose and REMOVE it.
