This was an enhancement, not requested by users but intended to mimic
applications from other sources.  To scroll only one line, set the
preference variable toolkit.scrollbox.verticalScrollDistance to 1.

You can go to about:config to set this, but I prefer editing file
user.js in my profile so that I can annotate it with a comment:
  user_pref("toolkit.scrollbox.verticalScrollDistance", 1);
  // vertical scroll only 1 line per click of keyboard or scrollbar arrow
The semi-colon at the end of the first line is mandatory.  Any line
beginning with // is a comment.  Note that changes to user.js become
effective only if SeaMonkey is completely terminated and then re-launched.

If you want to scroll some other number of lines (e.g., 2), just change
the 1.
