Unfortunately seems like I'm hitting the same issue but because of CSS Grid. This is the site: https://cv.l3x.in

On macOs 10.14.6 it prints all right in Chrome and Safari, on Firefox 72.0 it's truncating the "Work experience" section at the first page break, skipping to the next item in the unsorted list.

The same content rendered without any display: grid prints correctly: https://cv.l3x.in/work

The same quick workaround works though, i.e. replacing display: grid with display: block
