Firefox 19 does not honor lockPref settings

Since several months I have successfully used "lockPref" to lock settings (specifically, proxy settings) on Firefox 17 and Firefox 18.
I am running Ubuntu 10.04, and I have used the file:
Firefox 17 did not always honor those settings. Often it did, sometimes it did'nt. I also found that there is another file location some people are using (?), and this is:


To be sure, I put my settings into both of them. With Firefox 18, it did honor those settings. So this was working well.
(Note - I have NOT used any byteshifting or anything, as one can read was necessary for old versions of Firefox. There being no clear documentation by version, I feel I have no way to tell if this is actually still required or not. It was working without any byteshifting on Firefox 17 and 18.)

I just upgraded to Firefox 19 - and voila (of course, I might say) again the settings are not being honored. This time they are NEVER honored. They are JUST IGNORED, EVERY TIME.

This is very upsetting - can someone please point out what is now changed?
Do I now need to use yet another configuration locking file location?
Or do I suddenly need to do this byteshifting thing - if so what is the procedure right now for this?

Settings I am trying to lock are:

//set proxy server settings
lockPref("network.proxy.http", "a.b.c.d");
lockPref("network.proxy.http_port", yy);
lockPref("network.proxy.https", "a.b.c.d");
lockPref("network.proxy.https_port", yy);
lockPref("network.proxy.no_proxies_on", "localhost,");
lockPref("network.proxy.type", 1);

Use a mozilla.cfg file in the Firefox program folder to lock prefs or specify new (default) values.

Place a file local-settings.js in the defaults\pref folder where you also find the file channel-prefs.js to specify using mozilla.cfg.

pref("general.config.filename", "mozilla.cfg");
pref("general.config.obscure_value", 0); // use this to disable the byte-shift


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

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

Did not work for me - I need the DEFAULT settings for ALL USERS. So when a new user account gets created, then it should take the defaults from there. As mentioned above, it does "mostly" files you put into etc-firefox-pref- folders.

Maybe it is best to continue the conversation in your other thread about locking prefs, so I'm closing this thread.
