Yeah, looks like the Facebook web app does a version check, and hasn’t blessed the OS version yet. It’s a facebook bug.I did some digging, and it appears to be a common complaint over at MacRumors concerning the latest security patch. I don't use Facebook, so I can't comment personally, but one user claims to have a fix by changing the user agent, rather than forgoing the patch, which is kinda important.
Addendum: It may have something to do with the parenthesis "(a)" for the Safari version number.
