Hi Curt,
You might want to check out
Add Facebook button to Safari Toolbar . I have never used it so I can't say if it will mess up your Safari browser or not so please do some homework before installing any third party extension such as that to see if users are having any problems with it first.
And make sure to read the system requirements first to make sure it is compatible with your version of Safari and OS.
Sorry if that is not what you are looking for.
good luck,
LS 🙂
