Okay, I added the local-settings.js. Firefox launches correctly, but it still isn't pulling the correct settings. It is pulling user preferences from /home/username/.mozilla/firefox/user.default/user.prefs. Is there a way to tell it to override user preferences and only use the config file specified? <br />

Thanks Steve. I'll try adding a local-settings.js with the two
general configs and seeing if that helps. Just out of curiosity, if
one of your students goes to <a href="about:config" class="moz-txt-link-freetext">about:config</a> or <a href="about:cache" class="moz-txt-link-freetext">about:cache</a>, do they
see the settings?<br />

only difference I can see at this point.</div>

Thanks for the reply. I have user and group
setup with nobody:nogroup and 755
permissions. Is this wrong? How do you have
your permissions setup? Currently we don't
have it setup as a local app. Thanks for
your help!<br />

I've been trying for a few days
now to get Firefox to cache pages
to /tmp locally for all users. I
updated to Firefox 7, then edited
the firefox.js in
/etc/firefox/pref to include these
lines -<br />
<br />
pref("general.config.obscure_value",
0); (supposed to tell FF not to
worry about byteshift)<br />
pref("general.config.filename",
"firefox.cfg");<br />
<br />
I then took a customized
firefox.cfg file and placed it in
/usr/lib/firefox-7.0.1.<br />

<div>This is what we do (to lock down
network settings and the like) and
it works. The only problems I can
think of are permissions issues on
/usr/lib/firefox-7.0.1/firefox.cfg
(can the user read it?) and whether
you have an error in the JavaScript
in the .cfg file? Then again this
is all run on the server for us (no
local apps), are you running Firefox
as a local app?</div>
<div><br />
</div>
<div>For what it's worth, we found
that many apps and even the Gnome
desktop itself didn't work that well
with nfs mounted home folders for
the students. We've since moved to
having real local folder on each of
the LTSP server (we have multiple
load balanced) and we use csync (<a target="_blank" href="http://www.csync.org/" moz-do-not-send="true">http://www.csync.org/</a>)
to synchronize those with the
central file server on login/logout
and every 10 minutes they're logged
in. Performance went up
dramatically and the load on the
file server is almost nothing.</div>
