Yes, JFBConnect is still being maintained and we are staying up-to-date with login functionality. Google, Facebook and most other social network authentication still works. Unfortunately, Twitter changed their API to be pay-only earlier this year and we have not (and do not) plan to update to support it as the costs are extreme.
Finally, I apologize for the lengthy delay. We had an issue that was preventing us from responding to support requests but it is rectified now.
Thanks,
Alex
