Hello, i am silent deploying Firefox on many Pcs at a time. The Computers now have Firefox 14 on it and the people work with it well. I ve deployed it with setting changes in the user.js. Now i must deinstall the Firefox 14 and install Firefox 16 ... the firefox profile is still in the userprofile. Now i want to change silent one line in the user.js in my userprofile.... i do the new user.js in the <Programfiles/Firefox/defaults/profile> folder... but the new user.js do not copy in my userprofile and overwrite the old one... I am searching for an solution to add one setting in my user.js or pref.js in my old profile... Greeting Joe

hello manowar30, i think you can better achieve this by using the mozilla.cfg file in the programs folder. for reference refer to http://kb.mozillazine.org/Locking_preferences

You can use these functions in mozilla.cfg: 

defaultPref();  // set new default value
pref();         // set pref, but allow changes in current session (prevails user.js)
lockPref();     // lock pref, disallow any changes

You need to create a batch file.. to copy the user.js file into the profile directory. The problem is... 1st The directory generates a random name when installed. 2nd it places a . in the directory name it creates. copy will not work.

To get around this .. there is a simple "for" command you can place in a batch file and will do the trick. example shown below.


set folder=%APPDATA%\mozilla\Firefox\Profiles

for /f %%i in ( ' dir /a:d/b "%folder%" ' ) do if exist "%folder%\%%i\." copy /y "C:\pathtofile\user.js" "%folder%\%%i\">nul
