Because you can’t use the scroll bar on mobile, it’s impossible to get hold of.

Swiping is a pain if you need to jump up and down on larger pages.

It’s really easy on iOS at least. It shows up when you scroll. Holding on it causes a haptic click and now you can drag the scroll bar.

Speak for yourself. Firefox on my PinePhone is not pure overlay scrollbars like almost all other mobile platforms, and I certainly appreciate the ability to manipulate the scrollbar to achieve more scrolling with less effort, and to jump to different parts of long documents with it with just a touch rather than potentially multiple swipes.
