pretty simple stuff here. The distinction between 'firefox' and
'browser' is that the 'browser' needles I expect would also be
correct for other default browsers, while the 'firefox' needles
are specific to Firefox. We need '-kde' variants of some Firefox
needles where interface text is included, because the font is
Cantarell in GNOME but whatever the default 'sans' font is in
KDE - I suppose we should really use -thatfontsname rather than
-kde, but I can't think what it's called...
I couldn't do the 'log in to FAS' bit of the test since we don't
really have a sane way to provide a password while not exposing
it to the public.
