I was just looking for a similar answer and happened upon your post.

Unfortunately I can't help w/ everything but I can tell you why
window#config*{display:none;} isn't working for you.
It is because that line doesn't go in userChrome.css, it goes in
userContent.css. (I do have that working).

I had a very nice kiosk setup all working for Firefox 3.6 but they
have changed everything.
I was able to disable downloads by removing some files from omni.jar
and eliminating menu w/ userChrome.css settings.

The problem I am having now is removing the drop down firefox menu in
firefox 8. Or at least removing the "preferences" part. Also I can't
seem to modify omni.jar this time. I suppose they changed something
to discourage modification..maybe for security reasons.

I am happy to share my userChrome and userContent files, or even my
whole .mozilla file from before if you want to look through it. (It is
for Linux but I think the settings should be similar or the same for
windows). It is different for firefox8 though so it seems like I have
to mostly start over which I am not happy about.

I hadn't seen DOM inspector. Thanks, nice find.

I did finish modifications to my satisfaction this morning.
On earlier kiosk (which really was an internet kiosk) I forced full
screen and eliminated the panel on bottom so there was no way to
escape the browser which pulled up automatically upon system start.
This is actually not for a kiosk so full screen is not forced etc.

What I am doing is using DansGuardian with /squid proxy to prevent
certain sites from being accessed. So I needed to prevent access to
"preferences" (Called "options" in the Windows version but exactly the
same). In order to do this I eliminated the menu including the drop
down menu in tab bar. But before I did that, I set everything up the
way I wanted in normal preference (options) menu. I didn't have to use
about:config. although you could use that also. My changes included
network setup (through proxy), privacy options, file "save to" options
etc. I got rid of the drop down menu by un-checking "always show tab
bar" in "tabs" . There are no tabs, so this is not ideal, but its ok
for what I am doing. When everything was set up the way I wanted I
then copied userChrome.css and userContent.css files to the
user_profile\chrome (13i61gey.default ..the name is different for each
user). Placing these files eliminated the menu and eliminated access
to about:config when firefox restarted. Finally, I set the file
permissions for firefox user files to prevent non-root users from
being able to alter them. I don't think there is any way for ordinary
users to modify the settings now... at least I can't think of one.
This was on Linux but it should work exactly the same Windows.
Here are userChrome and userContent files I used if you are curious.
Best of luck.
