That is not the difference I was talking about. The differences are
that Firefox 3 has three different methods that don't exist in the WD
and the WD has three methods that aren't implemented (or are renamed)
in FF3. Also, FF3 does not implement the mediaType. That would seem to
be useful to have implemented because it could allow for faster
notification of user errors.

Firefox 3:


Working Draft:
   readonly attribute DOMString      fileName;
   readonly attribute DOMString      mediaType;
   readonly attribute unsigned long  fileSize;
   DOMString          getDataAsString()
   DOMString          getDataAsBase64()
   DOMString          getDataAsHexBinary()

(regarding FileDialog)

Thanks for pointing that out. That's pretty nasty. It's a good case
for removing FileDialog. What is the use case for FileDialog that
can't be fulfilled by the browse button?
