I was curious about that so I checked it out a bit. According to the discussion page there, there are many references to the name "fire fox" that predate Mozilla (mainly in Chinese though some people found English citations as well). But the name has been removed from the article anyway due to over-zealous Wikipedia editors (but I repeat myself).
