A little bit early, but oh well
My firefox just updated, and whilst doing so, I happened to see the link to the themes page. Now, we all know I'm a bit goofy, but I couldn't resist downloading the Halloween one, even though its only September. Let me tell you, its freaking cute! Black and orange and green too, and it changed all my buttons to Halloween appropriate images(ghosts, witches, jack-o-lanterns, and the likes). I higly recommend that if you have any mozilla browser you check out their themes. They rock.
