Steps for how to make Single name account (or) how to Hide last name on facebook:

Step 1: From your Mozilla Firefox browser, open your facebook account and go to "General Account Settings".

Step 2: Change language settings to "Bahasa Indonesia".

Step 3: Go to any of below links,

http://www.proxynova.com/proxy-server-list/country-id/

(or)

http://www.hidemyass.com/proxy-list/

Select Proxy country=Indonesia, port=8080 & click 'Update results'.

Now copy the proxy address of port - 8080 from those results.

In general the proxy address will in this format - 61.247.45.35.

Just for example I'm giving you this proxy = 61.247.45.35, try it,  but it may works or may not works.

Mostly select new proxies which was updated there recently. [Check the time of recently updated proxies].

While performing this process, some of the proxies may not work and some proxies will work just like 1 out of 3 trails. So be patient while doing this single name account process.

Step 4: Now you  have to change your Firefox browser proxy as shown in the below pictures,

Go to Tools > Options > Advanced > Network > Settings.

Now click  'Settings' and select "Manual proxy configuration:" - paste the proxy & port-8080 where you got from above 2 links-Proxynova.com or hidemyass.com and tick the box that says "Use this proxy server for all protocols" and finally click OK in settings dialog box.

Step 5: Now open your Name settings in your fb. Simply remove your last name or leave it as empty and then click 'Save Changes' .

Now your Facebook account is with first name without last name . 

Step 6: Now Change back your Language settings from "Bahasa Indonesia" to "English".

Step 7: After completing all steps, remove 'Manual proxy configuration:'  in Firefox Settings and select "Use system proxy setting".

That's it!!
