Does Adium support Facebook Chat?

Yes. You can use Facebook Chat in Adium 1.3 and later. Adium 1.3.3 and later is recommended as it features a greatly improved Facebook implementation.

More reasons to update from 1.3.2 or earlier

• On old versions of Adium, you can't be signed into Facebook Chat both in Adium and on the Facebook website at the same time. This isn't a problem in 1.3.3.
• On old versions of Adium, if you've set Facebook's website to the new interface, Adium cannot log in. Workaround: Set it back to the old interface. Fix: Update to 1.3.3.
