Default profile settings in mozilla-thunderbird

[Mike Fedyk <mfedyk@matchmail.com>]

Hi,

I'm using running thunderbird[1] debian testing, and noticed these[2]
files in /etc, but they don't seem to affect my configuration.  For
instance, there are references to ldap servers in [2], but prefs.js in
my $home doesn't say anything until ldap until I added it manually.

How do I set the defaults in a way that won't be overwritten on new
upgrades, and will be followed by new thunderbird profiles created after
 the changes?

Thanks,

Mike
