Proxy Settings (Moved) (Mozilla Firefox Group Policy)

What it does

If this policy is enabled, you can configure and lock network settings. Select the connection type and then fill in the appropriate sections. Due to a bug, you must select a value for the SOCKS proxy version. If this policy is disabled or not configured, the default network settings are used and user can change them.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: ProxyLocked, ConnectionType, HTTPProxy, UseHTTPProxyForAllProtocols, SSLProxy, FTPProxy, SOCKSProxy, SOCKSVersion, AutoConfigURL, Passthrough, AutoLogin, UseProxyForDNS
