CONFIRMED on WinXP trunk build 2002071108.

This is probably because the scroll event is fired when the mouse is pressed,
and enters the status-bar area.. I don't know if thats what happens, but I
assume so (the status bar is not there in full-screen mode).

Re: Comment 3
I would say that the event fires when the mouse exits the document area:
if you go to a page with an horizontal scroll bar, then the mouse works to
scroll down while selecting, but if there's no horizontal bar and the bottom of
the document is also the bottom of the scroll then the mouse can't go any further.

Adjusting Summary to reflect that the problem is only when going down.

(I've reassigned this to Core, because it applies to Firefox as well,
not just Seamonkey.)

This bug has become significantly more prominent now, because Firefox no
longer has a status bar; thus, this applies not just in fullscreen mode,
but in any environment where Firefox goes all the way to the bottom of
the screen, mouse-based selection does not scroll when the mouse reaches
the bottom edge.  Environments where this can occur include full-screen
mode, many Linux desktop environments (notably the default configuration
of GNOME 3, though it also occurs with GNOME 2 if you remove the bottom
panel, and with many other environments that don't have anything below
the Firefox window), possibly OS X as well, and possibly Windows if you
move the taskbar to the top or side of the screen.

As far as I can tell, selecting with the mouse will only scroll in a
direction if the mouse moves outside the content area in that direction,
not just if it moves to the edge of the content area in that direction.
So, if Firefox's content area extends to the bottom edge of the screen,
you can't trigger scrolling by moving the mouse to that edge while
selecting.  In the common case where a maximized Firefox has nothing to
the left of its content area, you can also observe this bug by going to
a page which scrolls horizontally, scrolling to the right, then
selecting some text and moving the mouse to the left edge while
selecting; notice that Firefox doesn't scroll to the left.  In both
cases, you can cause scrolling to occur by having a scrollbar to hover
over (right or bottom), having a status bar to hover over, or un-
maximizing the Firefox window.

Suggested fix: in addition to scrolling when *outside* the content area
in a direction, scroll when the mouse reaches the last pixel *inside*
the content area, so that it works to press against the edge.

Firefox (29) on Mac OS X also has this problem.

When the window goes all the way down to the bottom of the screen,
scrolling down with selecting with the mouse does not work, but
scrolling up works.

This bug 157456 has a wider scope. The occurrences of the bug are not
limited to full screen.

Title:
  Chrome/Chromium/Firefox doesn't auto scroll when selecting content
  downwards

Status in Chromium Browser:
  Unknown
Status in Mozilla Firefox:
  Confirmed
Status in Ubuntu GNOME:
  Confirmed

Bug description:
  When trying to select a long text, that goes downwards in the screen, it won't auto scroll.
  Seen's the same thing as https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/744580 but I don't think it is a problem in the browsers, since it affect all of them. My guess is that it's a Gnome bug that won't allow the mouse going out of the text area. I don't know if it's relative, but in programs that have a bar in the bottom, it start scrolling right after the pointer touch it. So my guess is that Gnome isn't allowing the pointer to go a bit deeper out of screen's edge, which is common in Windows for example. Maybe because of the pressure thing that brings the messages bar up. I didn't had this problem with Unity for example. If the screen is unmaximized, then it works normally.
