I like #2 a lot.
It was time for a re-branding. They did the Mozilla logo last year, this is looking good too.
I’m a Firefox guy, but IMHO this is a colossal waste of energy.
Kind of indifferent about it if you ask me. The designs are average with a hint of trying too hard. I do like what they did with the Mozilla logo last time. Over time, brands tend to lose character. Hope that doesn’t happen to Firefox or Mozilla.
