Answer: To enable or disable RLVa in “Firestorm” go to Avatar/Viewer > Preferences > Firestorm, select the tab “Extra” and check (enable) or uncheck (disable) the option “Allow Remote Scripted Viewer Controls (RLVa)”. Before the new settings will take into effect you will need to exit and start “Firestorm” again.
