Firefox for Mac 72.0.1 prints only 3 pages of a web page. There seems to be a problem with Print Preview or Apple's Preview application or both, their interaction.
I've tried all of the suggestions. I tried all the print options. I tried using the Print Edit extension. I disabled extensions. I used safe mode. I tried deleting all the Preview prefs. I tried deleting every trace of Firefox and Mozilla from my hard drive, then reinstalling Firefox. I deleted and reinstalled my printer drivers for a monochrome Brother laser printer HLL 2370 that is only a few months old. I'm running macOS 10.11.6
Web pages print correctly in Brave, Safari, and iCab. Therefore this is a problem with Firefox. It's a perennial problem that I have had for many years. I have ALWAYS had problems printing web pages in Firefox. It's always something. I don't understand how something so basic can continue to go unfixed when other browsers don't have a problem with it. I'm baffled by the whole thing.

Yes, that issue baffles me too, since the first day I started using Firefox in Aug 2002, when it was called Phoenix.

Works for me on Windows, hope it works as good on MacOSX.
Thanks for the fresh suggestion. But it didn't work.
What works for me is copying and pasting a web page into LibreOffice, which does an excellent job of maintaining formatting, including charts and many graphics and pictures. You can always download the picture to your hard drive, then drag and drop into onto your document. This wasn't an option for me until LibreOffice came to the Mac, so it's a great relief.
Take your pick. Or maybe... just don't look at all. I have never been a overly-printy person, especially from the web, so i had never noticed. But now i can't un-see what i just saw.
