I'm trying to set up "Firefox" for multiple users. According to the instruction files filled "channel-prefs.js" and "mozilla.cfg". The files are in the folder C:\Program Files (x86)\Mozilla Firefox\defaults\pref\. file channel-prefs.js: /* This Source Code Form is subject to the terms of the Mozilla Public

* License, v. 2.0. If a copy of the MPL was not distributed with this
* file, You can obtain one at http://mozilla.org/MPL/2.0/. */

pref("app.update.channel","release"); pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0);

file mozilla.cfg: // pref("browser.startup.homepage", "www.nix.ru");


Firefox 43.0.1 OS Windows Server 2012 r2

hi gre07, mozilla.cfg would have to go directly into the C:\Program Files (x86)\Mozilla Firefox\-folder where firefox.exe is located as well.
