on Firefox 52.0a1 (2016-09-30) when clicking print before the PDF loads: print preview preparing message is opened in a new tab and clicking ok on the warning message from the original tab with the PDF, opens print preview with the pdf loaded as expected. This was taken as a good build.

on Nightly 52.0a1 (2016-10-01) (64-bit) when clicking print before the PDF loads: a new tab is opened with Print preview preparing message, and going back to original tab and clicking ok on warning message loads only a white page from the PDF in print preview like in comment 0. This was taken as a bad build
