I have a UMBP and for some reason in Safari when I use 3 fingers to scroll down or up, it does not go to the top of the bottom of the page like it does in Firefox. The 3 finger "Swipe" to go forward and back works, but not the 3 finger scroll.
Is that a feature that Firefox built into their browser, or is there something wrong with my Safari? I find it ironic that a non-Apple product is making better use of the trackpad then Apple themselves.
