help, leaking DNS-requests with firefox and privoxy-tor

[Joerg Reckers]

I thought i have set up the firefox -> privoxy -> tor chain as instructed, but 
still, i am leaking DNS-requests.
On http://www.showmyip.com i get tor-server ips like 66.239.30.194 or 
128.42.98.102 or ...

BUT with etheral  i still see communication with the dns server i set 
in /etc/resolv.conf:

 DNS Standard query A www.showmyip.com
 DNS Standard query response A 67.15.74.5

What could i have done wrong? I am a bit lost. My setup follows, if you need 
more infos please ask

thanks in advance for any ideas, joerg
