I can't get lockPref("plugin.state.java", 2); to work in ver 35.0.1. I'm trying to lock this for a school district to take the PARCC test

I can't get the mozilla.cfg file to work in Firefox 35.0.1. I'm getting this error "Failed to read the configuration file. Please contact your system administrator"

mozilla.cfg // lockPref("plugin.state.java", 2);

local-settings.js pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0);

Thank you for the responses.

I got it working by placing the files in these directories. I’m using Mac OS X 10.7.5 and above.

/Applications/Firefox.app/Contents/Resources/mozilla.cfg /Applications/Firefox.app/Contents/Resources/defaults/pref/local-settings.js

Hi Dg58,

if you have set the local-settings.js file with the order : pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0);

then try with the opposite order :

pref("general.config.obscure_value", 0); pref("general.config.filename", "mozilla.cfg");

If you get ""Failed to read the configuration file" then that means that Firefox finds the local-settings.js, but doesn't find the mozilla.cfg file or that there is a problem with that file. Make sure that you have saved the mozilla.cfg file as a text file and that the file is in the Firefox application folder.
