I used firefox on mac, and tested safari and it works as well.

Are you running any of the firefox ad blocker extensions? I know that there are a few extensions that block the 'evil badness of porn' and common ad links for a 'cleaner surfing experience'.

I know refer.ccbill.com is blocked as well as most of the ad.aadmt.com sites that cnn/etc use for advertisements. Perhaps that site is blocked because it is mostly adult related content served over their CDN.
