Why do you assume that this was done by Thunderbird ?

Thunderbird is my only mail server that is why I assume it to be thunderbird problem is not logical this way?
There are several possibilities I can imagine here that don't involve a bug in Thunderbird:

1. Some virus on your computer used the external API of Thunderbird to create and send a message to people in your address book.
2. Someone obtained the username and password to one of your email accounts and used it to send messages to people.
3. Some spammer is sending messages to people and just happened to use your email address.
4. Some virus on the other person's computer added a message which appeared to be from you (by looking in their address book).
5. Someone is playing a prank on you and either dropped a message in the other person's mailbox pretending to be you or used your machine while you weren't looking to send it and "erase" all traces of it.

It is possible to distinguish between some of these possibilities by looking at the message headers, specifically the Received headers and any SPF headers that may exist. These, assuming that a transit server was not compromised, will give the full history of the delivery of a message from source computer to the recipient's email server.
