DVC Website - Firefox on a Mac


I use Firefox on my mac at both work and home as my main browser. I have been trying to access the DVC site for a couple of weeks now, and I kept getting an error. They have been known in the past to have problems, so I just assumed the site was down. I went looking again, and found:

Firefox/mac: Error
Safari/mac: Works
Firefox/windows: Works
IE/windows: Works

Does anyone else use Firefox on their mac, and can they confirm it does not work for them?
