How do I change Firefox Proxy settings via command line on windows xp/2k?
Thanks
You could also use this Powershell script I wrote to do just this, and all other Firefox settings as well.

Using this you could easily manage Firefox using computer startup and user logon scripts. See the wiki page for directions on how to use it.
