firedragon-browser: Can't restore sync functionality

Hey!

I am currently trying to restore sync functionality but with no success. I created a ~/.firedragon/firedragon.overrides.cfg file and added:

unlockPref("identity.fxaccounts.enabled","");
pref("identity.fxaccounts.enabled",true);

unlockPref("identity.sync.tokenserver.uri", "");
pref("identity.sync.tokenserver.uri", "https://<privateURI>/token/1.0/sync/1.5")

After restarting FireDragon I have the “Sign In” Button back, but nothing happens after I log in. What am I missing here?
