Of course I prefer the mozilla way :)

It does seem fairly complicated to allow it to be set after the download 
is finished though. You do have the stream stored in .reponseBody, but 
at that point all encoding information has been lost. For HTML parsing 
(which I hope the spec will support in the future) there are a pile of 
rules used to guess the encoding, all of which would be useful to use, 
but can't be used if all you have access to is the unencoded responseBody.
