Free Proxy servers to Unblock Youtube, Facebook and other banned sites in Pakistan

Ban on Youtube in Pakistan and restriction of Facebook in offices and universities has increased the demand of proxy servers. Proxy servers work as an intermediary agent to send your request to web server. Proxy servers can bypass the filtered gateway of the country, as requests are sent from the country where proxy server is placed, so restricted website can be unblocked. There are three ways to use proxy servers. 

Online Proxy Browsers 
One type of proxy servers have their own online browser to display your request. Some top ranking proxy websites of this kind are: 
zendproxy.com 
proxywebsite.org 
space-links.net 
proxy-browser.net 
sslbrowser.com 

Proxy Server IP address in user's browser
In another method, users use their own browsers to open blocked websites. In this case proxy server IP address and port number need to be saved in browser. Every browser like IE, Mozilla, Chrome have network setting option where proxy server and port no. can be entered and saved. Many websites provide proxy servers IP addresses and port number. Some are free and some charge, the free ones are slower as compared to paid ones. Few famous proxy IP address list websites are: 
freeproxylists.net
www.ip-adress.com 
samair.ru 
newipnow.com 

VPN Proxy software
Third method is to use proxy software which creates a Virtual Private Network (VPN) to unblock restricted websites. Some famous software for this purpose are: 
HotSpotShield 
Gpass1 
Your-freedom 
SmartHide 
Proxpn 

All above three methods have their own plus and minus but they can be used for restriction free access to internet.
