I have a Solaris 10 box in a secure environment (no Internet) with Firefox 30 installed. I need to lock javascript in a disabled state for all users. I realize each individual user can toggle javascript with about:config, but that is only a per/user activity. I want to set the value of javascript.enabled to false for all users. Additionally, no user should be able to modify this setting.

Is there a location with a config or prefs file that will affect all users?
