List does not include a file extension I frequently attach to emails and does not allow any additions. The default application it uses to open this file extension is wrong and I can't change it. Windows default application for this file extension is correct but Thunderbird does not use it.

Can you be a little more specific? What file extension? What application? What are you doing when 'Thunderbird does not use it'?
