Comment 163 for bug 233901

I'm trying to follow the instructions in comment #7. In all.js, I've put:

pref("general.config.obscure_value", 0); // for MCD .cfg files
pref("general.config.filename", "firefox.cfg");

and it does appear to read /usr/lib/firefox-1.5.0.10/firefox.cfg, which has:

defaultPref("browser.startup.homepage", "resource:///region.properties");
defaultPref("general.useragent.contentlocale", "resource:///region.properties");

/usr/lib/firefox-1.5.0.10/region.properties:

browser.startup.homepage=https://www.cora.nwra.com/intranet

But I still get the system default. What am I doing wrong?
