Openfire 3.7.0

Jabber is one of the most common protocols in instant messaging clients because it has everything required to effectively establish direct communication with other people. Openfire makes use of it, thanks to which it has an ideal system for sending instant messages to anyone you want.

It works very much like a traditional browser, so it's easy to use even if you've never tried instant messaging before.

Openfire is highly customizable due to the huge amount of configuration parameters it has as well as the ability to install add-ons.
