I'm wondering if it's possible to use the Enterprise Policy Generator extension in New Moon...

Lord willing, I'm looking to block the proxy settings from being changed (or enabled/disabled.) I am able to do this on Firefox using the extension mentioned above. If it's not possible to use the Enterprise Policy Generator in New Moon, is there a way to block these settings from being changed using another method? If so, could someone give clear, easy-to-understand instructions on how to go about doing this? I'd appreciate it!

I'm using New Moon version 28.10.7a1 32 bit on a computer running Windows XP Home SP3 32 bit.
Regards...
