Do you believe the old mozilla suite had more code than FF does today?

Complexity isn't easy, but it's not that black and white. Just because the first time round it didn't work out so well doesn't mean it won't this time; especially since the circumstances are so very different.

In any case, things like personas are supported, but most of the complexity isn't in the browser; new functionality doesn't need to be tightly coupled to the browser - just exposed.

I actually think the problem isn't so much on the software side, it's organizational: trying to do too many things at once means making sacrifices.
