Thank very much, I find the answers in this website.

Here I refer to the production of a cmd file

cd /D "%APPDATA%\Mozilla\Firefox\Profiles"
cd *.default
set ffile=%cd%
echo user_pref("network.proxy.http", "192.168.1.235 ");>>"%ffile%\prefs.js"
echo user_pref("network.proxy.http_port", 80);>>"%ffile%\prefs.js"
echo user_pref("network.proxy.type", 1);>>"%ffile%\prefs.js"
set ffile=
cd %windir%
