Version: (using KDE 4.3.1) OS: Linux Installed from: SuSE RPMs If you get online using the facebook extension you are not shown as online for your friends.
From: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=566531 Reported by: Nicolas DEGAND <nicolas@degand.net> When I log in into Facebook through the plugin, I appear to be connected to fellow Facebook users. This until someone tries to send me a message. At this point, I now appear disconnected for other Facebook users.
This can be considered fixed, because facebook now uses xmpp for chat.
