Comment 199 for bug 233901

It works, ;-)
it was a stupidity of mine, I had saved a copy of greprefs/all.js as filename all-copie.js and has it kept the .js extension is was read and probably overloaded the all.js calls .
now I have rename it to .old and these calls are well executed
pref('general.config.obscure_value', 0);
pref('general.config.filename', 'firefox.cfg');

So my lockPref("browser.startup.homepage", URL ); now works fine .
However I still cannot do ldap calls :-( , but that last since early realeses of firefox, cf
