I was reading a Harry Potter fic in the Pit of Voles (FanFiction.net, for those of you who haven't heard that particular epithet). I was going along, reading a great fic, when all of a sudden, when I hit the "next" button, it took me to an entirely different fic. The URL was right, but everything else wasn't! I almost freaked--especially when I saw the author's name was "Virusgod".
Then I tried it in IE, and it took me to the right page. WTF is up with that, Firefox?
