Nexus is an application that unblocks Facebook in nations and territories where the website is banned. The user of Nexus will only need to run the program once, and Facebook can be accessed in territories that block Facebook without needing to use a proxy service, however they must be sure to include "https://" at the beginning of their URL address. Note: Certain browsers will only work for some computers when the user attempts to open Facebook after running Nexus. Once Nexus is run once, the user will need to test out their browsers and determine which browser will work for them.
