Midori Sans is a semi-condensed sans-serif font with styling similar to Frutiger, M+ or Myriad, but narrower and with a taller lowercase height that helps improve readability at small sizes. It should be well-suited for
use in menus and dialogs. Regular and bold weights are included.

Unlike Workplace Sans/Gothic, Midori Sans is completely unhinted, so
it shouldn't have the same issues as the former when it comes to
choosing a hinting level to use in Mozilla.
I've actually been using it (development versions) as my default UI
font in SeaMonkey for several months. I think it looks REALLY nice,
personally -- much better than Workplace Sans, even though it doesn't
attempt to resemble WarpSans at all.

Here's a screenshot of my SeaMonkey properties dialog:

Unfortunately, I haven't figured out how to completely change ALL the
UI fonts... default form text, some tooltips, the about:XXX pages and
a few other things seem to still use Workplace Sans. But at least my
menus and dialogs look really nice now... :)
