I just tried to reproduce but the scrolling was not smooth for me. I'm not sure what's different about our configurations. Maybe there is something in your firefox profile? Could you try in a fresh profile? Have you always been seeing this or did it just start happening recently?

Oh maybe you are referring to the way that the fixed/sticky header smoothly animates into view from the top after scrolling down? I think that is an effect created by the page using either css and/or js. The smooth scroll preference doesn't have any affect on what content pages do for their own animations.
Even with a new profile, either Firefox or support.mozilla.org converts Page Down to animated scrolling. it would be even worse if it were smooth instead of choppy.
Of course it may be a bug with support.mozilla.org rather than Firefox.

I converted the video to single frames in png format. I can not see any evidence of smooth scrolling in the frames. There is one frame before scrolling, one frame after all of the scrolling has completed, no frames in between. After that the header animates into view and the scroll position is changed slightly, but I'm fairly certain that is caused by the page js or css.
