Plain text compose shortens lines to 46 characters not 72

[Budgie3]

By default I do not use HTML when composing messages and my messages have very short lines, about 46 rather than the 72 default limit.
Why is this and how can I adjust this so lines are closer to the 72 limit before wrapping.
Believe me I have tried reading the advice on this site but not found answer to my question.

Just wanted to add I also get inconsistent and unwanted line breaks if I edit on different machine although the settings are supposed to be the same.

In Edit/Preferences/Advanced/General/Config. editor, mailnews.wraplength controls the wrap width. Right-click, Reset, to change it to the default 72, or Modify to something else. A value of 0 (zero) wraps to the window width.

See http://kb.mozillazine.org/Plain_text_e- ... hunderbird for information about some other settings for plain text.

Many thanks for the suggestion. If it had been that easy I would have done it already. The setting is already at 72.
What next please?

The wrapping for plain text messages has been buggy for as long as I can remember, though it seems better in version 68. The best workaround I found was to compose a HTML message with no HTML.
