OK, but more involved than it should be for Facebook
Facebook integration was a nightmare and I suggest you NOT using this module for FB. For one, instructions on inputing the BASE URL on Facebook is confusing and easily repairable with more explicit instruction. Even then, you'll have to change it to a designated web other than your own URL for this to work.
As for Twiiter, Linkedin, Google, OpenID, Yahoo, and AOL, it works fine without much hassle. I did get a token error message, but it appears to be OK now. The other concern is that they are using this module to track your site's traffic.
Solution: I kept the JomSocial Facebook Connect and added a module for OTHER logins separate using their module.
