Personal opinions: I like the header bar a lot because it's consistent
with other GNOME sites! Generally, most text looks pretty small to me in
FF37 and the grey background makes me miss enough text contrast. :-/
I do support gradual changes (and we've made some as can be seen in
https://git.gnome.org/browse/bugzilla-gnome-org-customizations/tree/ ).
For example, having a GNOME-style top bar would be awesome.
I would love to test and help with CSS patches against GNOME Bugzilla's
current theme!

But to generally push Mozilla's custom Bugzilla theme forward and make
it potentially available in GNOME Bugzilla (with customizations), the
best way is to first help upstream Bugzilla developers to include
Mozilla's custom theme in the upstream Bugzilla code base.
