This component is perfect for my needs: with a single keystroke, I am able to add or remove the signature on the fly. My favourite feature is "Add signature at cursor position".
Unfortunately, some month ago this component stopped working due to Thunderbird updates.
Big thanks for updating Add Signature so it supports version 60.*!
