This used to work, I promise! It was a facebook chat client that translated incoming and outgoing messages to your desired languages. Shortcomings (and reasons for being currently useless) include using Bing's translation API which is no longer free, and the fact that the "client" is the actual facebook.com site, but with everything but the chat functionality stripped out at runtime, and then re-styled. Amazingly hacky. Used to work/look great. Now, nothing. Beware.
