Description

[josh]

Attachment: Two PDFs showing documents printed in Firefox 55 and 56

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170824053838

Steps to reproduce:

I created a webpage to print contracts for our company - either as PDF or on paper.


Actual results:

In Firefox 55 everything looked fine, but in Firefox 56 the printout is messed up (see attachments). On screen, it looks as expected.


Expected results:

Fix the print option, that's all ;) .

Hi josh,

Thank you for reporting this.
I would be grateful if you could attach the pre-print html file in order to find regression point.

@:dbaron
Your bunch of patch seems to cause the problem. Can you look at this?

FYI -- I'm aware that a bunch of regressions from bug 1308876 turned up after it hit release (after none were reported while it was on nightly or beta).  See https://bugzilla.mozilla.org/show_bug.cgi?id=1308876#a30998038_3881 and below.  I'm going to try to look into them over the next week or two -- and hopefully there are fewer underlying problems than there are bug reports -- but these can be somewhat difficult bugs, so it might take a little time.

Any progress after 9 months? This bug is very serious - no one can use firefox for printing even on latest ESR version.

The testcase in comment 7 was fixed in this range, which means it was fixed by bug 1427141.

Comment 13

[Ryan VanderMeulen [:RyanVM]]

Do the tests landed in bug 1427141 cover this case or should we land the test from this bug still?

Comment 14

[Mats Palmgren (inactive)]

The tests for bug 1427141 is probably enough to cover this case. This bug doesn't really have a reduced testcase anyway.
