O segmento é um pouco antigo, mas quero compartilhar minha solução de qualquer maneira. Espero que isso ajude alguém. Nós tivemos um problema semelhante e queríamos adicionar os certificados do windows store no firefox. Então eu criei um script para fazer isso. De qualquer forma, você pode alterá-lo para as suas necessidades: Basta adicionar ou remover as linhas em: create cfg_file_name.cfg [...] e insira o que você precisa, por exemplo. echo pref("browser.startup.homepage", "http://superuser.com"^); para a página inicial inicial e assim por diante. Lembre-se de definir o ^ antes do último), caso contrário não funcionará!
Desde a versão 49, você pode fazer assim:
@echo off
setlocal enabledelayedexpansion

:: This script will add two files, which will change about:config parameters of
:: Mozilla Firefox. You can change the name of these two files and remove or add
:: parameters according to your needs. Renaming the files could be essential, if
:: a user creates own files and you don't want to overwrite them.
::
:: If the two files already exist and the script is run, the complete content
:: of both files will be overwritten!
::
:: Note: You may have to run it with administrative privileges!
