I've had a better look at this now, and there seems to be a generic
server side solution through the content-disposition header (at least
for the versions of Firefox and IE which I have tested). If it is
specified, the default installs of both products always produce a
download dialog and don't open inline.
Sample apache config for mitigation:
<IfModule mod_headers.c>
<FilesMatch "\.pdf$">
Header append Content-disposition "attachment;"
</FilesMatch>
</IfModule>
