How do I configure NPM to Trust the firewall issuer for HTTPS proxying?

I am attempting to use NPM in an environment behind a corporate firewall. Said firewall intercepts all https traffic and signs it with its' own CA... Is there a way to "trust" this CA so that NPM can actually work?

Found the solution... (Ignoring SSL Certs)

npm config -g set strict-ssl false

Thanks to this thread in google groups.
