Recently, Facebook introduced Facebook chat – which allows you to chat with your Facebook friends in realtime similar to IM, as compared to post-message-on-wall-and-wait-for-replies kinda communication that Facebook users endured so far. A slight problem would be that to use this feature, users need to be logged in and be on Facebook’s site.
Not any more. eionrobb and Saturn2888 have coded a plugin for Pidgin which allows you to chat with your facebook buddies using the Facebook Chat IM service. Just grab the plugin 6, copy the the .dll file to your C:\Program Files\Pidgin\plugins\ (or equivalent) directory and restart Pidgin, if you’re on Windows.
For Linux users copy one of the .so files to either /usr/lib/purple-2/ (for 32-bit Linux), /usr/lib64/purple-2/ (for 64-bit Linux), /usr/lib/pidgin/ (for Nokia/Maemo) or ~/.purple/plugins/ (if you don’t have root access) and restart Pidgin.
Don’t forget to grab the icons too. Just Extract the facebook_icons.zip file to the pixmaps/pidgin/protocols folder. On Windows this is generally C:\Program Files\Pidgin\pixmaps\pidgin\protocols and on Linux, /usr/share/pixmaps/pidgin/protocol and enjoy chatting.
