Firefox doesn't show the size of mime type in the save-as dialog box
for me.

Why can't they use a GET request and start downloading in the
background.  This is what I thought that they did anyway.  Making a
HEAD request and then a normal request seems rather pointless to me
(since the resource could change size or mime-type between the two
requests).

The best option would then seem to be that when online a HEAD request
to WWWOFFLE is a non-cached HEAD request to the end server (unless the
cached page is new enough not to make the request).  It seems a
strange way for the browser to work, but I can't think of a better
work-around for WWWOFFLE.
