While I welcome the update (long time coming!)...
BEWARE - the site looks horrible on Firefox! 
Everything is out of place and it's all pushed over to the left. You would think that any modern-day web designer worth his/her salt would be over their IE-centric vision by now.
Come on FIRST - we know you can do better!
It turns out that the common Firefox Add-on "Adblock Plus" does really bad things to the site. So, please ignore my comments above, but be forewarned if you use Firefox and that Add-on.
BTW - First time I've ever seen Adblock Plus do that to a page. The new FIRST site is built with something called Ektron. Google gives lots of hits concerning incompatibilities between their tools and Firefox 3.x.
OK - I was too quick to criticize, and I apologize. It seems I had Firefox running with the old site still loaded in the browser. Instead of restarting, I just did a page reload, and got garbage! (I just wish I'd taken a screenshot!). When I turned off Adblock Plus and reloaded, it must have done a "real" refresh, and I got the site as it should look. So I falsely assumed that Ablock Plus was the culprit.
Since then, I went to another computer and
www.usfirst.org loaded just fine with Adblock Plus running. So... "never mind"
