It's not just you, I'm on a speedy desktop with lots of RAM, and Firefox and Chrome both choke on that page for both initial loading and responsiveness, and scrolling. This is a dev machine, about as good as Google's average user is going to get, and the only reason I tolerated the experience was to see how bad it was. I would have otherwise closed the tab given that I don't think I have an interest in a Pixel.
