i do it know for some years, the whole thing is based on the internet
explorer feature to find proxies.

and there is some goog documentation from microsoft for it:
http://technet.microsoft.com/en-us/library/cc713344.aspx
http://support.microsoft.com/kb/934864

there are two ways..
   - via DHCP (some IE have a bug, so they cut of the last char of the
     option 252)
   - via DNS  

and IMHO firefox is only using the DNS method
