[K12OSN] Hardcoding proxy/user setting in mozilla for all users

[Wilson]

Is there a way to hardcode the proxy setting to all users? Right now I have
to manually set the proxy setting (http://192.168.0.254:8080) on all the
user accounts by logging in. Also, what about cosmetic changes like setting
the theme to modern and enabling tab browsing? There has to be a better way
then hard coding it per user. Thanks!
