Proxy Settings

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.

Supported on: Firefox 60 or later, Firefox 60 ESR or later

Don't allow proxy settings to be changed.
