Subject: How to set global/system Firefox prefs for new users?
For Firefox in newly added user profiles, I have a few modest
preconfiguration goals: 1) Customize the toolbar to add Print, History,
and Tab Groups. 2) Set new tabs to display a blank page.
I would think that #1 might be accomplished either by setting
pref("browser.uiCustomization.state", "{long string copied from my
user profile pref}");
or else by copying my initial user's xulstore.json to
/usr/lib/firefox/browser/defaults/profile or
/usr/lib/firefox/defaults/profile. (Or by doing setting the pref AND
copying xulstore.json.)
But to zero in on setting the prefs: I failed first with what I took to
be the standard Firefox methods.
Then I found
https://help.ubuntu.com/community/UbuntuLTSP/FirefoxOptimize, and
though
it was written for *buntu 12.04, I'm assuming that it's probably still
valid for 14.04. (I'm running Lubuntu 14.04.1 32-bit.) And it
indicates that global/system prefs should be placed in
/etc/xul-ext/ubufox.js. But my prefs seem to be either ignored or
subsequently overridden/overwritten.
(And yes, xul-ext-ubufox is indeed installed.)
How do you successfully do these things in 14.04?
John,
I hope this isn't just noise but it of use. Below are my notes but
they do apply 12.04 I'm afraid. Also, it's not for ltsp-pnp, it's for
old-style ltsp with a chroot (which is why there are additional notes
about copyiong the files to the chroot at the end).

============================
Firefox config (including setting homepage and proxy)
Configure proxy
sudo nano /etc/firefox/syspref.js
lockPref("network.proxy.http","address.of.proxy");
lockPref("network.proxy.http_port",80);
lockPref("network.proxy.ssl","address.of.proxy");
lockPref("network.proxy.ssl_port",80);
lockPref("network.proxy.type",1);
lockPref("network.proxy.share_proxy_settings", true)
Configure homepage
sudo nano /etc/xul-ext/ubufox.js
Uncomment homepage line...
pref("browser.startup.homepage",
"file:/usr/share/doc/xul-ext-ubufox/example-homepage.properties");
sudo nano /usr/share/doc/xul-ext-ubufox/example-homepage.properties
Change to:
browser.startup.homepage=http://www.ourhomepage.com
Copy all three files to chroot and rebuild image
sudo cp /etc/firefox/syspref.js /opt/ltsp/i386/etc/firefox/syspref.js
sudo cp /etc/xul-ext/ubufox.js /opt/ltsp/i386/etc/xul-ext/ubufox.js
sudo cp /usr/share/doc/xul-ext-ubufox/example-homepage.properties
/opt/ltsp/i386/usr/share/doc/xul-ext-ubufox/example-homepage.properties
Reimage and restart services
sudo ltsp-update-image; sudo ltsp-update-sshkeys; sudo service
nbd-server restart; sudo service tftpd-hpa restart; sudo service
isc-dhcp-server restart
It's interesting that your recipe uses a standard Firefox
configuration location for the network proxy stuff and only uses the
ubufox provision for homepage. This bolsters a thought that it is
only selected prefs that ubufox aims to govern (whatever exactly those
are) which must be configured via ubufox.js.
Looking at the installed files for the xul-ext-ubufox package, I find
3 .js files at /usr/share/xul-ext/ubufox/defaults/preferences:
ubufox.js
ubuntu-mods.js
000system.js (but that is just a symlink to /etc/xul-ext/ubufox.js)
And I don't see any prefs in any of those files that would seem to
bear adversely on what I want to do.
Following your recipe I tried putting my prefs in
/etc/firefox/syspref.js, but they too were either ignored or overridden.
There is a lot of conflicting and obsolete info out there, including the
locations of the Default Preferences Files given in
http://developer.mozilla.org/en-US/docs/Mozilla/Preferences/A_brief_guide_to_Mozilla_preferences
But that article is correct in what it says about Changing Defaults,
option #1. And following that I created
/usr/lib/firefox/browser/defaults/preferences/all-nameofyourchoice.js
with content (make sure to terminate with an end-of-line e.g. hit Return):
pref("browser.newtabpage.enabled", false);
This has the same effect as clicking the gear tool on a new tab and
choosing Blank rather than Enhanced or Classic.
So now I know how to propogate extensions and default preferences to new
users. The only thing I have not been able to accomplish is adding
Print, History and Tab Groups to the default Firefox toolbar.
