What input method (mouse wheel, trackpad, keyboard arrows, autoscroll, etc.) are you using to scroll?

I'm using mouse wheel to scroll, but the problem exist when using keyboard arrows as well.
Can you describe in a little more detail what you are seeing? I tried reproducing this (Fx 54 beta 1 on Windows, 64-bit build). I loaded amazon.ca, clicked on the electronics department page which was longer, and scrolled as fast as I could with the mousewheel. The behaviour I saw seemed reasonable. I also tried scrolling by holding down the "down" arrow on the keyboard.

If this issue is new to 54 beta 1 and wasn't there in the 53 beta, please use mozregression [1] to narrow down when this issue started. Thanks!

I think it might have something to do with the AMD Radeon driver 17.4.2 I was using. I updated the driver to 17.4.4 and the problem no longer exists.
