Ok, when I use the spell check feature (not like I ever do that :eek

I sometimes click on "add to dictionary" and then this really screws me up. I'm like crap! and then I am always worried I spelled those words wrong again. After almost 2-3 years of using firefox, one can imagine that this has occurred fairly often, and my list of words that have been added to my dictionary is rather huge. My question is simply this:
Howz do i d-1337 meh dic shun airy??
(how do I access the dictionary so I can purge it :P)
