[ubuntu-uk] Locking down Firefox settings

[Rob Beard]

Hi folks,

I was wondering if anyone knew how to lock down the settings on Firefox 
on Ubuntu 8.04?

Basically I'm nearly done setting up an LTSP Server and I want to make 
sure that no one who logs on can fiddle with the settings.  I've got 
Tinyproxy and Dansguardian installed and working but only if I manually 
specify the proxy settings.  I found something about entering some 
settings in /usr/lib/firefox/firefox.cfg which I have entered (details 
here: http://m.linuxjournal.com/article/9044) but I'm finding I can 
enable and disable the Firefox proxy settings and alter the rest of the 
settings as I please.

I did try Firehol to force the proxy transparently but it stopped the 
LTSP clients from booting unless I enabled a whole lot of ports on the 
Firehol configuration (I got so far but got stuck on the nbd ports).

Just wondering if anyone knows how to do this?

Ta,

Rob
