Implemented but SSL is not the default, Firefox will always bitch about mixed content issues for https://www.fsynth.com app. or any online Fragment app. with fas enabled because we cannot provide a browser 100% trustworthy certificate for localhost/127.0.0.1 for obvious reasons... so if fas is SSL-enabled, Fragment app. is online somewhere and the websocket connection is with "wss" protocol, it will still not work under Firefox unless Firefox config. change happen or an exception is explicitely made, Firefox will still bitch about insecure contents due to self-signed certificate, this is unsolvable (but if you think otherwise, do tell us, please!) and still a critical concern.

For now, Fragment apps. should always use HTTP, this is the requirement to allow fas to be enabled everywhere without issues.
