This second Firefox 3 Release Candidate is a preview release of Mozilla's next generation Firefox browser and is being made available for testing purposes only.Firefox 3 is based on the Gecko 1.9 Web rendering platform, which has been under development for the past 34 months. Building on the previous release, Gecko 1.9 has more than 14,000 updates including some major re-architecting to provide improved performance, stability, rendering correctness, and code simplification and sustainability. Firefox 3 has been built on top of this new platform resulting in a more secure, easier to use, more personal product with a lot more under the hood to offer website and Firefox add-on developers.

It starts quite alot quicker than RC1 for me, especially with lots of windows saved from last time, much quicker for that
I gotta see this to believe
You're correct.
'overall' best browser out there in my opinion... it's only 'real' competition is Opera i think.
p.s. im on a pc though.
Go Firefox!
also problems with the plugins that care yet not compatible ...
At least use Cocoa, it will be a lot faster and consistent with the rest of the OS.
but my fx2 works pretty good so i wont mess wit it
Hopefully someone releases a plugin for people who prefer the old drop down, and I'm sure the new address bar can be changed with CSS or a plugin.
Despite all that, I'm still happy with it. It's definitely faster than FF2 was for me, and the only way I'm uninstalling it is if a new release comes around.
