Hi,
nowadays the javaFX login example (https://github.com/restfb/restfb-examples/blob/master/src/main/java/com/restfb/example/LoginJavaFXExample.java) is not working anymore. Once the facebook page is loaded, it just shows "Facebook is not available in this browser".
Could just be related to javaFX itself and there's nothing that can be done from the restFB side but I wanted to inform you about this
