How can I manually add my signature in Thunderbird ? I have set up my Thunderbird signature and it works perfect on my new messages and replies and forwards. But , sometimes I need to edit the forwards and don't want my signature in the middle or at the top of the message. So I delete it and edit what I want. Then I want to insert it at the bottom. But can't find any option to insert signature manually.
Thunderbird 17.0.2 Ubuntu 12.04.01
