tor with ubuntu 12.04 and firefox, not using vidalia

This is how I configured it.
sudo apt-get install tor   # to install tor
sudo vi /etc/tor/torrc   #edit torrc to use only certain country exit nodes, in this case Great Britain
ExitNodes {GB}
StrictExitNodes 1
Now run tor in background in a window
tor &

tor should run and perform a handshake.
if it says tor is already running, say

sudo killall tor

Configuring Firefox to use the proxy we just set up:

got to prefrences > advanced >network > settings

select manual configuration
and in the socks host type 127.0.0.1 and port as 9050
and select socks v4
done

refresh firefox you shd be online now

to test, goto bbc iplayer and play any video, it shd work now.
