Yes! And, fwiiw, when I am updated The Tech Files, I have 30+ tabs in FF 3.0.1 and it does not slow down. I thought I would try that with Chrome ... don't - at least not yet!
It has the strength of Google and OpenSource behind it - but the 'Big Brother' fear in me is concerned. The EULA was changed not b/c it was wrong, but b/c of OpenSource/community response. I hope I am wrong - but for now at least, FF 3.0.1 still has the overall advantage for the enthusiast, imo
Regardless, all of the innovation is good - it serves to refine all of the options and that makes a Geckling happy
