.reg file example :
``` [HKEY_CURRENT_USER\Software\Policies\Mozilla\Thunderbird\lockPref] "network.proxy.type"=1 "network.proxy.http"="192.168.1.42" ``` The Mozilla's properties name can be found at about:config (for Firefox) or in the Advanced preferences tab in Thunderbird. Most of the properties can be found at http://kb.mozillazine.org/About:config_entries. A lot of preferencies are in common for Firefox, Thunderbird and Seamonkey.
It is possible to set default or locked preferences. Default preferences will be reset at Firefox, Thunderbird or Seamonkey startup, the user can edit them. Locked preferences will be set one time, the user cannot edit them, they have a grey tint.
The extension starts as soon as Firefox, Thunderbird or Seamonkey starts and apply the preferences found in the Windows Registry.
The extension uses XPCOM components to access to the Windows Registry (nsIWindowsRegKey) and Mozilla Preferences (nsIPrefService).
An icon shows informations at the right bottom of the window (not in Firefox, should be fixed later).
