We'll try to get some UX input here. We usually try to match the behavior of the browser for various interactions, but here I think it makes more sense that page down goes down a page as it does in any other pdf viewer.

I see this behavior also, usually around Page 3 or 4 of any PDF.  Workaround is either (1) use the mouse and scroll bar to scroll down, or (2) use Adobe Acrobat Reader rather than FireFox's built-in reader to view PDFs.

I know this variant (last seen in 45.5.0esr): If you press "page down" the PDF view toggles between the first part of the first page and the second part of the first page.

Comment 4

[John David Galt]

I've seen that behavior too.

Oddly enough, both versions seem to happen when running Windows but not on Linux.

It has this behavior on my linux machine (Ubuntu MATE) as well. Here's my run of lsb_release -a.

Distributor ID:	Ubuntu

works for me with Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:97.0) Gecko/20100101 Firefox/97.0

Can you still reproduce this bug / behaviour?

I could not reproduce the bug with some random PDFs in 91.4.1esr either, so it can be assumed to be fixed.
