OTR is only suitable for real time communication. For posting messages on facebook (as for email) you would use PGP. This used to be possible using Firefox with the FireGPG Addon, but the developer stopped working on it and a release wasn't even made for Firefox 4.
FireGPG was brilliant. It would detect blocks of PGP in the page, and add "Decrypt/Verify" links to the appropriate place in the page, and would let you easily encrypt/sign data. I can't believe nobody took over development. I keep meaning to learn how to write Firefox addons specifically so I can take up this project, but I haven't found the time.
