Status changed to 'Confirmed' because the bug affects multiple users.

Changed in firefox (Ubuntu):
status: New → Confirmed

Having the same symptoms, but this was resovled for me by turning off smooth scrolling (as commented on Can anyone confirm if turning off smooth scrolling resolves this issue for them, as well?
