The Australian English Dictionary -- or as I like to call it, AussieDic, is a modern Australian dictionary for Firefox

Please don't send complaints or report the Firefox extension for profanity. The purpose of the dictionary is to include all coloUrful language used in Australia. As such there are plenty of bad words, slang and racist remarks included in the dictionary that may not be appropriate for all. Simply don't type the words and they won't need correcting.
