Matt informed me that the new Kairosnews site design was breaking in Firefox with the navigation menu over on the right.

I had experienced it, too, during the upgrade. The fix is to clear the private data for the browser. Must be some legacy CSS or javascript files being held in the browser cache from the old site.
BTW: the site does look better in Firefox than IE (for those still stuck in MS land). Safari users let me know if there are any problems.



Safari
seems ok. Only browsed a bit and posted this comment, but everything seems to work.
