Customized setup for deployment of Firefox 4 : How to integrate addons & prefs (seems different than 3.6.x)

Question

I'd like to silently install Firefox 4 using customized prefs, but it's seems different than the 3.6.x versions.
How does it work with the new "folder architecture" used in Firefox ?
* For 3.6.x, using the -ms switch install Firefox silently, and i integrated addons & prefs by :
- copying pref.js + localstore.rdf + mimeTypes.rdf + content-prefs.sqlite + bookmarks.html to "localized\defaults\profile".
- extracting all *.xpi addons into the extensions install folder "nonlocalized\extensions".
* For FF 4 the -ms still works, and i tried to copy my addons in "core\distribution\extensions\", but all of them do not install, and I don't see any "localized" or "profile" folder for the prefs..
Thx a lot in advance !

Hi guys, here are some informations that i found and combined. These preferences/customisations ARE TESTED and WORKING!!
First of all, extract your "Firefox Setup 4.0.exe"
'''Silent installation without desktop icon:'''
Create a "nodesktop.ini" at the same place you can find the setup.exe (root directory after extraction) containing following text:
[Install]
DesktopShortcut=false
'''Run''': Installationfolder\setup.exe -ms /INI="CompletePathToInstallationFolder\nodesktop.ini"
'''Disable Import Wizard:'''
Create: InstallationFolder\core\override.ini containing:
[XRE]
EnableProfileMigrator=false
Many options have to be set in InstallationsFolder\core\defaults\profile\prefs.js These directories and the prefs.js File have to be created first. Then make following entries:
'''Use wpad:'''
user_pref("network.proxy.autoconfig_url", "YourWpad.dat");
user_pref("network.proxy.type", 2);
'''Set startup homepage:'''
user_pref("browser.startup.homepage", "http://www.YourPage.com/");
'''Don't show browser rights:'''
user_pref("browser.rights.3.shown", true);
'''Don't ask if FF should be default browser:'''
user_pref("browser.shell.checkDefaultBrowser", false);
'''Dont't show FF welcome homepage at first run:'''
user_pref("startup.homepage_welcome_url", "");
