For Firefox 69.0.3 (64-Bit), Win 7, x64.
i experienced that taking a fullpage screenshot stops at 32767px in height with the firefox screenshot fullpage button. The console-comand :screenshot --fullpage does not take any screenshot at this large page. :screenshot works as expected
half of the article is in the screenshot but not the bottom.
full pages screenshot should scroll all the way down the page to get all the content
