After a lot of looking at the firestorm code, I had to add web_profile_url to the LoginResponse in our Robust (grid) server so it is available gridwide to all our users. I am also using the oath hook that Firestorm does, when you first log in. So the internal web browser in Firestorm knows who the user is, and can allow them to post to their profile. It is not for the faint of heart. lol We have an older Robust, so the web_profile_url might not be necessary on the newer one.
