What sick manner of sorcery is this?
I started over with a fresh copy of Firefox Portable and the page is still rendering strangely. Except the same installation of FFP renders differently on a different computer on a different network!
This is almost as much fun as the black rectangle thing.
ETA: I even get the same user agent string from http://www.whatsmyusergent.com even when BoingBoing is rendering differently.
I guess the only thing I can think of is that there might be some hopelessly obscure access permissions involved on this one computer when I’m running FFP from the USB drive.
