Unblocking Facebook is not as straight forward as it may seem when using a web-based proxy. There are a few factors which come into play. Two issues are the software being used and if JavaScript is available. There are a few common PHP scripts which are typically used by proxy owners. They are Glype, PHProxy and Zelune. There are also some other less common ones like Surrogafier and Happy Proxy. Try to seek proxies which use Glype because the latest version comes standard with a module for Facebook functionality. In other cases, it is simply a matter of unchecking the ‘Disable Scripts’ option and allowing cookies in the proxy settings. Try different configurations and see what works.
