Firefox is the only Browser trying to bring desktop sanity to mobile.
Chrome on iOS also has save as pdf, have to press share, then print, then the share icon again at the top.
I used to use the markup feature as a workaround.

is that a theoretical issue because I've never had any problem with page rendering in Firefox, it's been a major for a long time.
