I currently use Firefox on Windows with a policies.json located in "C:\Program Files\Mozilla Firefox\distribution" to ensure some required settings like a proxy server or SSO-portal as home page are in place, so users unable to read a documentation can still use the system. Now I need a browser without proxy for some applications. Currently I use a portable FF, but that's twice the work for updates. While I could just add another profile to the system FF and add a Icon, it still would use the global policies, as such locking me from changing certain values.

Is there any command line argument to ignore policies for this one session, specify another one or change the policy-file to ignore certain profile names?
