It is also impossible to scroll on desktop Firefox, unless I first turn of CSS style sheets, then it will scroll just fine.

thank you, much better!

I don't really care about the loading, I know that HN traffic can overwhelm sites. The scrolljacking, on the other hand, is infuriating, especially replacing the standard "swipe to go back/forward" with "swipe to go down/up".

The issue isn't with the loading but the overridden scrollbar behavior. It's pretty much impossible to scroll smoothly on any of my devices.
