When using the vertical scroll bar by left-clicking and dragging it, you can
cause the mouse to "stick" by also right-clicking the scroll bar and releasing
the right-click, point to the border so the resize cursor appears, then release
the left button from the initial left-click.  The vertical scroll bar will now
scroll as the mouse moves up and down within proximity to the scroll bar.

I actually kind of like using this bug as a feature, though!  hehe

Reading through the other bug report summaries, it appears that bug # 287959 and
280405 appear to be related to this issue.  However, there wasn't enough info to
be sure.

Reproducible: Always

Steps to Reproduce:
1. Left-click the vertical scroll bar and hold it down (starting the drag operation)
2. Right-click and release the vertical scroll bar while still holding down the
left button
3. Move the mouse to the border of the window so that the resize cursor appears
4. Now release the left mouse button and the scroll bar will follow the cursor
as you move it, so long as the cursor is within close proximity of the scroll
bar and not outside of the form boundaries.

Actual Results:  
I can scroll a web page verticall just by moving my mouse up and down without
any buttons.  To release the scrolling state, simply just left-click again.

Expected Results:  
Use this as a feature when you right-click on the scroll bar .. hehe.  Call it a
sticky scroll bar.  I think the real problem is in the right-clicking of the
scroll bar shouldn't "release" some scrolling state so that the other events
don't occur when you mouse-over them.

I also see this happen when i do the steps you outlined. I tried to do this with
MSIE, but could not reporduce it there. I would consider this isolated to Firefox.
