Because of your post, I happened to open IE after a long long time (I am addicted to Fx). In that my avatar is been displayed.. But why not in firefox? It was seen all these days?
FF ocassioanlly shows "[name] [rep description]" instead of blobs. for me. so i get a string of blabbers under the user's number of posts.
I am also addicted to Fx but never have this kind of problem, may be clearing of your cache will help you.
