Facebook for Adobe AIR is an application that runs on your desktop. You log in with your Facebook account and can then read your News Feed and publish content to your Wall and friends' News Feed. You must install Adobe AIR first. The application can be downloaded into any operating system that supports the Adobe AIR framework. Currently, the developers have not updated Facebook for Adobe Air for a bit of a long while, and when you log in an error message reading "You must log in to use that feature" is displayed.
