face? How do I make it stop? Whenever I type "lol" on Facebook chat it comes up as a big laughing smiley face and all my smiley faces are big and animated, my friends' faces are the normal small faces and they can type lol without it coming up as a face. How do I change mine?

I don't like these big animated faces I liked the small faces I used to be able to use.

Is it something to do with Firefox, or can I change it in my settings?
