Does not work in the latest version of Thunderbird 78.4.0, since the option to add text is missing when you go to 'Tools' - 'Add-on Options'.

Thanks for the feedback. It indeed works as described.

This was a change in Thunderbird (on which I has no influence ... I don't know why this was changed ...). Now you have to go to 'Tools' - 'Add-ons' - find the entry 'Standardtexter' - click on the 3 points on the right side - choose 'Options'.

works fine... but the text is always inserted at the beginning of the message. Nevertheless, into several situations, it would be useful if the inserting is made at the cursor location (as for inserting a matched civility at the end of a message, for example).

I absolutely agree - maybe I will be able to introduce this functionality (insert the text at the cursor position) in a later version of the Add-on.
Edit: The version 1.0.2 now includes the possibility to insert the text at the end of the message or at the cursor location.
