Newbie needs help

[Bob Williams <security@xxxxxxxxxxxxxxxxxxxxx>]

Hi,

My system is openSUSE 11.1 x86_64 with KDE4.2.4 desktop, using linux kernel 
2.6.27.25-0.1-default, and Firefox 3.0.11.

I've installed Privoxy and Tor, but I'm having difficulty with the setup. I 
can launch both programs:

18:58 user:~> privoxy /etc/privoxy/config
Jul 23 20:29:33.391 Privoxy(7fb481fa96f0) Info: Privoxy version 3.0.10
Jul 23 20:29:33.391 Privoxy(7fb481fa96f0) Info: Program name: privoxy
Jul 23 20:29:33.410 Privoxy(7fb481fa96f0) Info: (Re-)Opening logfile 
'/var/log/privoxy/logfile'
20:29 user:~> tor -f /etc/tor/torrc
Jul 23 20:29:44.752 [notice] Tor v0.2.0.35. This is experimental software. Do 
not rely on it for strong anonymity. (Running on Linux x86_64)
Jul 23 20:29:44.752 [notice] Initialized libevent version 1.4.5-stable using 
method epoll. Good.
Jul 23 20:29:44.752 [notice] Opening Socks listener on 127.0.0.1:9050

but when I select torbutton preferences (having selected 'Use the recommended 
proxy settings for my version of Firefox', and 'Use Privoxy'), and click the 
'Test settings' button, I get...

Tor proxy test FAILED! Check your proxy and Privoxy settings.

I have a hunch it must be to do with permission settings, somewhere, but ???

I've opened all the relevant ports in my NAT router

Any suggestions?
