Giving a complete path while setting config path for "general.config.filename", as I want to lockdown configuration values differently for each user. I want to be able to do the below in all.js pref("general.config.filename", "%USERPROFILE%/mozilla.cfg"); but it doesn't seem to work. Is there a way of doing this. I greatly appreciate any approach of a way to be able to set the lock down config file path on a per user basis.
