I am trying to connect to a IM account (WebEx connect - Protocol: Jabber/xmpp) with Thunderbird 15 but it fails to connect. It doesn't throw any error just says "Not Connected". Pidgin works perfectly with the same setting what I provided in Thunderbird 15. So the question is Will Thunderbird chat account(xmpp) support libnss3 Do I debug and collect info, when Thunderbird tries to connect to a chat account? I'm on Ubuntu 12.04
