Attachment: bug.pdf

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0

Steps to reproduce:

i have a div with display:flex and my div has several tag p. height of div is very large.
(i use bootstrap 4 for create this my html)

Actual results:

when print page, just print one page and do not break page and do not print other page. and show blank page before and after first page.
because bootstrap 4 use "display:flex" for class(.row).
we do not have problem in bootstrap 3 because in bootstrap 3 there was not "display:flex".
you can open this page "https://getbootstrap.com/docs/4.0/getting-started/introduction/" and you can see problem when see "print preview" of this page.

Expected results:

print all of the content in seperate page

Thanks for the report. This is an old known bug, bug 939897, and I believe it's on our near-term roadmap as part of some printing improvements we're planning to focus on in the next few months.

Firefox Nightly (2020-05-13) can now print the page without any data loss. Fixed by bug 1622935.
