That option has been removed from the main options area of TB3. It's now
hidden in an advanced configuration area. I couldn't find it myself
until I did a little google for it:
"Tools => Options => Advanced => General Tab => Config Editor => (and go
down to find) Mailnews.wraplength
you can change the setting to 80 or 90 or whatever you want the wrap to
occur at."
I do think the default setting of 72 characters is a good one and it
shouldn't be changed without a very informed reason for doing so,
I wonder why they removed the setting ?
Thunderbird seems to use some of the same engine as a web browser, and
that Config Editor is similar to about:config in their browser. A pretty
bad UI change, to bury it in there.
I set the wrap to 1000 on mine, so I can control where a line
wraps. It allows a longer URL to be posted in one piece,
up to the point that the USENET server rules prevent posting
because the line is too long. Doing that isn't of much use
on a site like AIOE, because they police line length there
pretty closely (130?).
