Thunderbird supports secure email connections without any additions.  If your ISP supports it, you need to get the connection details from them.  It is usually on a different port.  If they don't support, you can't use it.

If you're talking about encrypting the contents instead of the connection, here's a supplier for certificates: http://www.comodo.com/support/products/email_certs/thunderbird.php   Here's an article about using PGP with Thunderbird: http://lifehacker.com/#!180878/how-to-encrypt-your-email

Thanks.  Yes, I am asking about encrypting contents  and making my own personal cert.  Any freeware certs worth looking at?

Never heard of a 'freeware cert'.  Things like SSL certificates have the overhead of identifying you and verifiying your identity thru the certificate.  I can't see anyone doing that for free.  A self-signed cert has the problem of not being traceable to a Certificate Authority so they are often not accepted.  http://en.wikipedia.org/wiki/Certificate_authority

Interesting, that page says there are Free certs.  This search brings up a few: http://www.google.com/search?q=free+digital+certificates

Read the article on PGP, it's free.  Note that encrypting your email requires giving the receiving party a key to decrypt it and they have to have the software installed.  It's not universal or automagic.
