As it turns out, somehow the mouse driver was in an unstable
state, because when I rebooted the system, the problem went
away.  What was happening was that when I scrolled FF or TB
to the bottom with the thumb-wheel, and then scrolled up, one
notch - it went into a behaviour that either changed something
in another page (instead of scrolling up in the page where the
mouse focus is) or opened something else in yet another pane.
I think this is not normal behaviour, but I could be wrong.

But for now, I do not have this problem after rebooting, so I will
not pursue this issue any further, but interestingly - it only happens
with FF & TB.
