Citrix Configuration of Firefox using Mozilla.cfg
We're publishing Firefox through Citrix which works correctly. We want to set a few settings that are locked and some that are set as initial preferences. When creating the mozilla.cfg with minimal settings that are locked, everything works correctly. When using additional settings that are not locked we get the "Failed to read the configuration file" error. We've tried to remove some of the settings to make is as basic as possible and still get the message.

Chosen solution
The defaultPref() function applies if there isn't a user setting (it only changes the current default value), but doesn't have effect if the user already has changed the default. The pref function is always issued if you start a new session, but the user can override that for the current session only and changes are lost. Prefs that are locked via lockPref() can't be changed at all.

You can't use user_Pref (should actually be user_pref) in mozilla.cfg
You can use these functions in mozilla.cfg:
defaultPref(); // set new default value pref(); // set pref, but allow changes in current session lockPref(); // lock pref, disallow changes
Thanks. I knew something was wrong. So what is the difference in using pref vs defaultPref in this instance. Won't setting prefs set the default settings a user will get as well?
We want to lock a few settings down but set a default for others while still allowing the user to change as desired.

Aha. Thanks you so much for explaining the defaultPref cs Pref. That helped immensely.
I now have this as my config but get an error

Does it help if you remove the comment lines at the start and have the line with // as the first line?
Does it work with the starting like // and only a few lockPPref lines?
Just a few remarks about some of the prefs.
Prefs like these are no longer used in Firefox 4+
lockPref("browser.history_expire_days", 30); //clear history after 30 days
lockPref("browser.history_expire_days_min", 30); //minimum 30 days to keep history
lockPref("browser.link.open_external", 1); // open pages in new tab
I'm not sure why you want to enable http pipelining by default. Not all servers may support that feature and if not you may encounter problems like missing or wrong images showing.
A value of 1 opens a link in the current tab, to open in a new tab you need to use 3
lockPref("browser.link.open_newwindow", 1); // open pages in new tab
Is there an equivalent setting for the history? We need to ensure we keep the history for 30days.
As for pipe-lining, I pulled the settings off my browser which I've tweaked a bit. It's good you mentioned it, I'll pull them out for the corporate version.
Thanks for catching the newwindow setting.
You're welcome
There is no time limit in Firefox 4+ versions for the history.
Firefox determines automatically how many pages can be kept without affecting the performance.
You can see the current value via the reads-only pref places.history.expiration.transient_max_pages on the about:config page.
See:
Thanks. So I got rid of the pipelining, history and corrected the open tab settings and I still get the error. Here is the current config.

The problem seems to be this line:
lockPref("mozilla.widget.raise-on-setfocus"); //disable focus stealing
If I comment it out then it works.
Don't you just love end users. I posted before I started commenting out the settings to check. You were more correct than you know. Somehow I had lockPref("mozilla.widget.raise-on-setfocus"); //disable focus stealing defaultPref("mozilla.widget.raise-on-setfocus", false); //don't focus new tabs duplicating the setting one of which (you pointed out) had incorrect parameters.
All is working now. Thanks for all of your help. You are wiser than Jor-el. I'd call you Brainiac 5.
You're welcome
