I wish websites would stop messing with the scrolling behavior.
"But it adds motion" was the classic reply.
There is nothing wrong with art. It is a great thing, I hope to see more art in the world. However, if the goal is sharing information, which is supposedly the goal of a fairly large number of websites, art needs to be secondary to sharing that information. And then those things that add motion, whatever: you're adding art and harming the real purpose.
The comment above shows this type of people don't understand it. Yet they are the ones getting hired due to formal qualification. Those who do are at the intersection of design, engineering and computer science. The latter give you enough experience to understand the culture to recreate familiar _look and feel_.
I found no problem scrolling. Either Firefox on Android doesn't support whatever trickery they are doing, or they reverted it.
Ublock on Firefox mobile seems to keep scrolling unfucked on this page for me. (Designer/"dev" of this page still sucks wet hobo socks.)
