How to install Firefox 4 silently with customizations?

I know that with Firefox 3.6, one could extract the installer, modify files such as "nonlocalized\defaults\pref\firefox.js" and "localized\browserconfig.properties", and then install Firefox silently with these modifications by running the "setup.exe -ms" command.

Now that Firefox 4 is out, I tried duplicating this behavior but found that the files mentioned above were nowhere to be found within the Firefox 4 installer. How, then, can I install Firefox 4 silently with customizations such as having the profile migrator disabled, a custom home page, etc.?

I have discovered that after extracting the Firefox 4 installer's files, the core\override.ini file can be created and set up to disable the profile migrator. Also, the core\defaults\pref\firefox.js file can be created and set up to disable the default browser check and such. However, I have yet to figure out how to set the home page. Does anybody know?
