I'm seeing an issue with the Facebook Authentication Plugin. If I don't have a facebook session and need to login into facebook after clicking the Facebook link in Liferay it wants to keep me in the new window that was opened and not return me to my origiinal Liferay browser window.

Can something be done to stop this behavior.

This looks like a virtual host configuration issue.
