Want to keep in touch with your Facebook friends throughout the day? Here we’ll show you how to easily add Facebook chat to the popular multi-protocol chat client Pidgin.
First, make sure you have a username for your Facebook account (link below). This is a relatively new feature for Facebook, so if you’ve had your account for a while you may need to choose one.
If you already have one, you should see it listed instead.
Now, open Pidgin, and click Manage Accounts.
Then select XMPP from the Protocol list.
Now, enter your Facebook username without the facebook.com part (e.gyour.facebook.username, not http://www.facebook.com/your.user.name). Then, enter chat.facebook.com for the Domain, and enter your standard Facebook password. You can check the “Remember password” box if you’d like Pidgin to automatically sign in to Facebook chat.
Now, click on the Advanced tab, and uncheck the “Require SSL/TLS” box. Also, make sure the Connect port is 5222. Click Add, and your Facebook account is added to Pidgin.
Now Facebook will show up in your list of accounts, with the firstname.lastname@example.org.
Your Facebook friends will show up directly in your Buddy list, complete with their full name and Facebook profile picture. Any users that are not in a group will show under your standard list, while ones in a Facebook group will be shown in a separate group. You can move which groups your Facebook friends show up in, just like you can with other chat contacts.
And no matter if your friend is logged in on the standard Facebook website or through another chat application, it will work the same as always.
This is a great way to keep in touch with your Facebook friends throughout the day. If you like Facebook chat and already use Pidgin, now you can keep from switching between programs and just chat with all your friends from a central location.
