It's always "Has my device freeze up? Oh no, there seem to be some change happening when I try to scroll, maybe if I scroll more it will work again?"

Any sane browser should let users disable it for all pages.

Any sane browser should also act like <video>, <audio> and <canvas> are unknown tags unless you allow that specific website to use them. Yet somehow, browsers are no longer user agents.

The site doesn't scroll at all on Firefox(X11) with ublock and umatrix, even when the non-tracking sites are enabled. In Brave browser it somewhat works in a janky way, but given that the site apparently brings a 24-core threadripper with 128GB RAM to it's knees, it certainly doesn't inspire confidence in the product, which otherwise looks pretty good.
