Having used Mozilla since 0.6, I think I can safely say this release is BY FAR the fastest. Render speed is at least on par with Safari and Chimera-- and in some cases much faster. I think the way the 3 browsers collect and render the page has a lot to do with the differences. At any rate, this is an excellent product, a MUST for developers, and just a solid app. Yes, it has some bloat... but I don't mind and it doesn't interfere with what I do. Kudos to the mozilla team!
