Uncontollable scrolling?

[GregM]

All of a sudden something has taken control of my Firefox pages.
When I go to a page it scrolls to the bottom of the page all by itself.
If I take the scroll bar at the right side back to the top it just goes to the bottom again.
I think it is haunted.
Help?

Apparently it was the logitech mouse.
I swapped the one I was using for another and it quit.
Never seen that before.

my main mouse, a logitech M720, does odd things when it gets dirty inside, or is on its way to old age. The scroll wheel tilts left and right, etc, and can do odd things when gummed up
