hi, please see https://wiki.mozilla.org/CA:AddRootToFirefox for a couple of ideas.

thanks... just a little above my head. Where do you go to set the preference "security.enterprise_roots.enabled"

your browser information said that you are on firefox 47 - this particular method will only work in newer versions of firefox though.

in order to set the preference for all users of a computer see the Configuration section in the article at https://developer.mozilla.org/en-US/Firefox/Enterprise_deployment (otherwise those settings can be tweaked when you enter about:config into the firefox address bar - this only affects the current user/profile though)

Thank you for the help. I'll play with that and see how far I get.

I set up an autoconfig in defaults/perf

// Just a comment perf("general.config.filename", "mozilla.cfg"); perf("general.config.obscure_value", 0)

then edited mozilla.cfg and added my change // try lockPref("app.update.enabled", false); pref("security.enterprise_roots.enabled", true); lockPref("app.update.autoUpdateEnabled", false); lockPref("extensions.update.enabled", false); lockPref("extensions.update.autoUpdateEnabled", false); catch(e) { displayError("mozilla.cfg", e); no workie do I have the syntex right? its dose not seem to be doing any of the line items

Note that you made a typos in the local-settings.js file (perf instead of pref):

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

OK I fixed the typo Thanks. still no joy. So I removed everything from the default file except what i want to happen

// Just a comment pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0)

// try pref("security.enterprise_roots.enabled", true);

also tried it with and without a  ; after the last line.
