Which buttons did you try on the drop-down panel to fix the problem? Here is an example PDF -- https://www.jeffersonscher.com/ext/Allrecipes_example.pdf -- showing:

(1) Printout from MS Edge for reference
(2) Printout from Firefox 75 without any modifications (content after page 1 is lost)
(3) Printout from Firefox 75 after clicking the "Allow Page Breaks *LIGHT*" button on this extension's drop-down panel to fix the pagination
(4) Printout from Firefox 75 after also clicking the "Use Basic Fonts" button to make the text searchable, which is useful if you are printing to PDF

Hopefully this example illustrates how it is designed to work and will get you the results you're looking for.
