In a corporate environment, it's sometimes handy to pipe web traffic through a proxy server. Unfortunately, the standard version of Firefox doesn't allow for any Active Directory Group Policy management but there is an easy way to configure new workstations so that any user who logs in is automatically set to 'auto-detect proxy settings for this network'.
After installing Firefox, simply modify the prefs.js file in:
C:\\Program Files\Mozilla Firefox\defaults\profile
and insert the following line:
user_pref("network.proxy.type", 4);
and every new user profile created on that workstation will have the option automatically enabled.
Of course, this works assuming you have the auto discovery for proxy servers properly configured on your network.
