How to copy an new user.js over an existing one in the profile
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

hi manowar30, you mean that the editing user.js file does not saved in the profile folder?
thank you
No, i already have an user.js in my profile. now i install the new version of firefox but the new user.js do not overwirte the old one in the profile...
i ve copied it to ../firefox/defaults/profile
from there it should be copied in the profile but it do not overwrite the old one in the profile...
I thing you must try madperson's reply (the locking preferences)
thanks again
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
