Totally wild shot in the dark - recent Mozilla have an onboard PDF viewer written in javascript called pdf.js http://en.wikipedia.org/wiki/PDF.js It's callable from within other javascript via chrome:// or resource:// references, but sometimes people don't get it right: http://superuser.com/questions/614002/how-to-open-pdf-js-in-firefox-via-chrome-url My guess is that somebody else didn't quite get it right, and is trying to get to the hostname when they intended to get to the javascript. pgpnqC0LkwArK.pgp Description: PGP signature
