When I do some scrolling with the middle button, often the page suddenly makes another jump and scrolls down after a short delay. This is very annoying if you just fixated on a sentence and the page moves away underneath.
System:
- Windows 7
- Firefox 10 – tried smoothscroll on/off
- Microsoft Wheel Mouse Optical – driver version 8
Already tried:
- another mouse
- another Wheel Mouse Optical (same problem)
- new drivers
- cleaning the mouse
- about:config -> smooth scroll

I know you've tried with another mouse as well, but just for luck, did you try another mouse in an alternate usb port ??
Next Goto Control Panel > Mouse > Wheel tab > and Change the Vertical Scrolling value to an increased/decreased value and see if there is any difference
