Firefox stutters

I am running FIrefox 40, WIndows 10. I have already tired disabling hardware acceleration, however the browser is running extremely slow, and when scrolling down the website stutter, glitch and jerk. Anyone else having theses issues?

This only happens with smooth scrolling enabled, which I would prefer to have enabled.

You can check graphics section on the troubleshooting information page for error messages about the graphics display diver being blocklisted and hardware acceleration disabled.

I turned off web GL as described, but the issue is still there. My graphics card drivers are up to date also.
