I am trying to find out how to disable the browsing history and ability to save passwords via console commands or editing a config file for CentOS 6.5+. I have tried many options, and have it only partially working.

Settings work when launched via console (/usr/bin/firefox, or just firefox) by adding the following to /usr/lib64/firefox/defaults/preferences/all-linux.js: pref("browser.privatebrowsing.autostart", true); pref("disable.password.save", true); pref("places.history.enabled", false);

However, these settings do not affect firefox when launched via the task bar drop down (Applications > Internet > Firefox Web Browser). I can manually edit the menu item by right-clicking on Applications on the task bar, but I need to have a way that I can change it via console, so it can be scripted for security hardening purposes.

Anyone have any ideas on how to get this to work?? Thanks in advance.

hi xion824, please refer to the guide at http://kb.mozillazine.org/Locking_preferences on how to deploy/lock certain preferences. in addition, please note that the right preference for disabling the storage of passwords is signon.rememberSignons (has to be set to false in this case).

Note that a pref() call sets the pref on each Firefox start and that users are still able to make changes for the current session.

These functions can be used in the mozilla.cfg file:

defaultPref();	// set new default value
pref();		// set pref, allow changes in current session
lockPref();	// lock pref, disallow changes
