I think I blocked a website without realizing it - I suddenly can't access it anymore. It's just one website, everything else works fine. I can't visit www.Flickriver.com since Friday - Firefox/Safari/Chrome simply can't connect to the site anymore (Connection failed). This issue only occurs with OSX, when I switch to Windows (Bootcamp) it works perfectly and I can visit Flickriver.com. PeerGuardian and Little Snitch are installed, but even if I close these programs I still can't connect to the site - so that's probably not the problem. Did I change something in the settings without realizing it? What program in OSX does block websites? I deleted the Cache/Cookies btw., still the same problem. Thanks for you help!
