Do you have a shift key stuck down? The mouse wheel can do different things with the browser, depending on the keyboard modifiers.

Well, it is not a static issue, the problem is intermittent. I do get page up/down but if you "flip" the wheel up or down quickly (fast scroll), then the page jumps - it is very annoying.
Is it a mouse with extra buttons on the side? Perhaps one's become extremely sensitive to touch.
If you were to call this in, the company would come back with 'this is normal behavior' and close it out, because IT IS. I get the same thing on my Mac if I attempt to 'quick scroll' with the trackpad. No pretty, but that is how it works.

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.
