Opening GUI application via another user's permissions


I've logged in as zuki (startx ran as zuki), and I would like to run firefox on another users permissions i.e : zukip.

What I get when I try to do this is an export error if I understood it right... please help me to do this :

Code:
zuki@WhiteCastle:~$ su zukip
Password:
zukip@WhiteCastle:/home/zuki$ cd ~
zukip@WhiteCastle:~$ pwd
/home/zukip
zukip@WhiteCastle:~$ firefox &
[1] 4420
zukip@WhiteCastle:~$ No protocol specified

(firefox-bin:4436): Gtk-WARNING **: cannot open display:

[1]+  Exit 1                  firefox
zukip@WhiteCastle:~$ export

I can't guarantee that this is your only problem, but it seems at the very least that your xserver isn't configured to allow multiple users. You can allow others temporary access with 'xhost + username'.

Changing the + to - will remove the user.

hmmm...
Code:
root@WhiteCastle:/boot# xhost + zukip
xhost:  bad hostname "zukip"
root@WhiteCastle:/boot# xhost + zukip@WhiteCastle
zukip@WhiteCastle being added to access control list
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  109 (X_ChangeHosts)
  Value in failed request:  0xfe
  Serial number of failed request:  7
  Current serial number in output stream:  9
