I'm trying to do the exact opposite of How To Make Thunderbird Compose Mail With "Body Text" As Default?. So my current default setting for composition is "Body Text", but I want it to be "Paragraph".
Just doing it the opposite way of the accepted answer doesn't work: If I select Format⇒Paragraph⇒Paragraph (from the menu bar), it does the formatting for the current e-mail; when I open another message, however, it starts out with "Paragraph" selected, but as soon as I type the first letter of my e-mail, it changes to "Body Text".
Is this a bug? Can anybody reproduce this behavior?

I have found that to set the default to "Paragraph" or "Body Text", you need to navigate from the main menu:
Tools->Options->"Composition" region -> "General" tab
In the HTML section, find the option for "When using paragraph format, the enter key creates a new paragraph"
Select that option if you want "Paragraph" as the default. Deselect that option if you want "Body Text" as the default.
