Comment 164 for bug 233901

Don't know why your defaultPref doesn't work, but I confirm that it doesn't for me neither .
 I finally resigned to set:
lockPref("browser.startup.homepage", "http://www.int-evry.fr/" );
in my /usr/lib/firefox-1.5.0.10/firefox.cfg
So it does set the homepage to http://www.int-evry.fr/ but then it's "mandatory", users cannot change it :-( , defaultPref, was, to my opinion , preferable to set a homepage and still letting people the ability to chang it . but apparently it doesn't work :-( .

Anyway, I hope there's a larger comuntity using autoconfig in mozilla/thunderbird/firefox/seamonkey ... it's a very valuable feature for large scale enterprises, keep it running !
