JFBConnect doesn't have specific integration for JoomBri. However, our social authentication features register 100% standard Joomla users that all other extensions can use. Additionally, you can easily add social sharing features to JoomBri content and other areas of your site.
The only extension specific integration we normally provide is for profile and avatar support for pulling in that data to your site. Even without that, JFBConnect can enable a speedier registration process and add lots of social network integration features to your site.
I hope that helps explain,
