It seems bizarre to positively remove something like scroll bars which probably existed and worked without any specific action at all.

I wonder if they are mis-detecting the device being used? Maybe the site "thinks" it is a phone rather than a laptop/desktop.

Looks deliberate

html {
scroll-behavior: smooth;
scrollbar-width: none;
overflow-x: hidden;
overflow-y: scroll;
max-width: 100%;
}

and they have plenty of browser/phone specific stuff in the html, so I
doubt they're serving up different content based on what browser they're
detecting, so have sent the wrong version.

As I said, I didn't even notice the lack of scroll bars, I always use
mouse wheel or space bar to whizz down a page (in TB as well as FF) a
page has to be *very* long for me to start reaching for the scroll thumb
to get to a specific part of it.
