Script Removing Proxy From Firefox User Prefs Js

2018-08-07 Josh Rickard

So, I was tasked with removing proxy settings from Firefox because of Webroot Desktop Proxy. ¬†Removing them from the %Programfiles% directory was easy, the hard part was the user prefs.js. ¬†Anyways, here’s a little script I created to remove Proxy settings and set them to No Proxy.

cd /D “%APPDATA%\Mozilla\Firefox\Profiles\” cd *.default set ffile=%cd% type “%ffile%\prefs.js” | findstr /v “userpref(“network.proxy.type”, 2);”>”%ffile%\prefs.js” type “%ffile%\prefs.js” | findstr /v “userpref(“network.proxy.type”, 0);”>”%ffile%\prefs.js” ren “prefs.js” “prefs.js” del “%ffile%\prefs.js” ren “prefs.js” “prefs.js” del “%ffile%\prefs_.js” echo user_pref(“network.proxy.type”, 0);>>”%ffile%\prefs.js” set ffile= cd %windir%
