Unable to connect to xmpp account with Thunderbird

Question

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

1. Will Thunderbird chat account(xmpp) support libnss3
2. Do I debug and collect info, when Thunderbird tries to connect to a chat account?

I'm on Ubuntu 12.04

Answer 1

The link shared by unor helped me to fix this issue.

The IM account was unable to connect due to certificate issue. Though I have a valid certificate it wasn't able to verify the certificate.

Here is the detailed steps on how to fix the issue.

Get the proper certificates

1. Get the certificate (If you dont have one) from pidgin account.

   • open Tools -> Certificates
   • select the appropriate hostname and click "Save" (file: certificate.pem)

2. Open Thunderbird -> Edit -> Preference -> Advanced

   • choose Certificates tab -> View Certificates
   • Select Servers and Click Import to add the download "Certificate.pem" and save it.

or

1. Use this link https://kingant.net/check_xmpp_dns/ to get proper server details.

   • open the link and enter "yourdomain.com" to fetch the server details
   • Copy the Target value in "Client records for yourdomain.com". In this case it is c2s.webex.com.webexconnect.com

2. Open Thunderbird -> Edit -> Preference -> Advanced

   • choose Certificates tab -> View Certificates
   • Select Servers

   • Click on "Add Exception..."

   • Enter the copied text under "Server Location:" with :5222 at the end (Replace https:// with c2s.webex.com.webexconnect.com:5222)

   • Click on "Get Certificate" and remember to tick "Permanently Store this exception" and save the setting by clicking on "Confirm Security Exception"

Adding XMPP account

1. Open Thunderbird -> Edit -> Account Settings
2. Add Chat Account
   • select xmpp
   • username: name@domain.com
   • password: .......
   • Resource: Doesn't really matter
   • Server: im.domain.com or the text grabbed from the URL(c2s.webex.com.webexconnect.com)
   • Port : 5222

Now we are good to go :)
