* Firefox UX Team will present “Firefox Design Principles” — learn useful principles to guide you when building a Firefox feature, what our audience looks like, and what makes us different from other browsers. If we can pull it off, this will be simul-presented in San Francisco (by Alex Limi) and Mountain View (byAlex by Alex Faaborg), and streamed via Air Mozilla — look out for announcement of exact time on dev.planning.
