I was using old version of thunderbird and line wrap was in "Option"
menu; but in new version "line wrap On/Off" disappeared.
How to disable line wrap?
They make this really impossible to find... Anyways, go to the menu Edit -->
Preferences, then scroll down go to the bottom option in the window that shows
"Config Editor...". Click to accept the risk and void your warranty. In the
search bar, enter "wrap". I think the settings you'll want are
mail.wrap_long_lines and/or plain_text.wrap_long_lines. Double click to change
the values. The changed settings should take effect immediately.
I hope this helps.
Kind regards,
Remco
