Facebook Chat Not Working in Ubuntu or Linux Mint

The Facebook XMPP API is being turned off. Trying to connect to Facebook Chat using an application like Pidgin or Empathy will no longer work and will throw a connection error. A replacement API for accessing Facebook Chat has not been announced.

This does not affect the ability to chat on the Facebook website or using Messenger. But you won’t be able to use unofficial apps such as Empathy, Pidgin and Kopete.
