I'm actually seeing it 'mostly' work in Chrome. What I'm seeing is that if I log in with the FB/Joomla account I created earlier, the page reloads but does not look like I'm logged int. If I refresh the page, then I see that I am logged in (which is from the "Auto login Facebook users" setting.
My guess is that the problem is from your configuration of Artio SEF. However, when I go to the Artio SEF component in the back end, I get a 404 page, which is strange. If you are using Artio (which you have the Artio SEF plugin installed, so I'm assuming you are), please check out the following question "When using Artio SEF, the Facebook Connect login does not work" and see if it helps:
