I think releasing earlier, faster is great -- execution is everything. I don't know if Mozilla needs to be afraid that Google is somehow getting ahead of them, though. I mean, yes, in terms of speed and simplicity, Chrome wins hands down. Considering how fast JagerMonkey is getting better, it doesn't seem that's as much of an issue to me (or at least, they're on the right track). But in terms of how much each company is churning out, I think Mozilla is keeping up just fine. Think about what they've talking about for the past year: Panorama, maybe a new privacy UI, Jetpack, application tabs, "HTML5" features -- this shows that they're actually thinking about the future of the browser. What has Google produced in the past year? Chrome jumped from v4 to v8 (and now v9, and soon v10). Extensions, HTML5 stuff, WebM, GPU-accelerated compositing, page prerendering. How much of this work was put toward Webkit, though? And why do you think they added all of this? To catch up with IE and Firefox. I just don't think it's a fair comparison.
