Status: RESOLVED INCOMPLETE

(Core :: DOM: Content Processes, defect, P3)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Firefox 55.0a1 20170424 32-bit and 53.0 64-bit on Windows 8.1

Tabs are broken after a content process crash in print preview: can't load pages, close action has to be triggered twice.

Steps to reproduce from bug 1359089:

This is due to print settings (see below):
0. Import the print settings from below and add them to the prefs.js file in the Firefox profile.
1. Open http://www.freiepresse.de/RATGEBER/REISE/Abflug-in-Prag-lohnt-sich-das-artikel9819481.php
2. Open menu File > Print Preview
Actual result:
Print preview prompt shown, one hyperthread is under full load.
Expected:
Print preview shown.
3. Cancel the loading of the print preview.
4. Try to load a page in the print preview tab or the tab with the original page.
Actual result:
Page not loaded.
5. Try to close the tab (e.g. by clicking the 'Close' button.
Actual result:
Tab still open.
6. Click the Close button again.
Actual & expected result:
Tab closed.

No idea if the PDFCreator printer is necessary for this: http://download.pdfforge.org/download/pdfcreator/PDFCreator-stable

This can be fixed by resetting these preferences:

user_pref("print.printer_PDFCreator.print_paper_height", " 11,00");
user_pref("print.printer_PDFCreator.print_paper_width", "  8,50");
user_pref("print.printer_PDFCreator.print_scaling", "  1,00");

to their initial values (in about:config).

This works for me, even with PDFCreator settings added to prefs.js as specified.  Tested on Win10 with Nightly build from 20171010
