Status: UNCONFIRMED

(Firefox :: Tabbed Browser, defect, P3)

Description

[Matheus Longaray (:mlongaray)]

Attachment: STR diff file

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36

Steps to reproduce:

Prior step:
- Either comment out https://dxr.mozilla.org/mozilla-central/source/browser/base/content/browser.js#3183 or apply attached diff file

STR:
- Make sure e10s is enabled
- Click on print UI button in order to print preview the page
- Close it
- Try to navigate on the print preview tab (extra one)


Actual results:

I was not able to navigate in such tab. Tab seems to be frozen.

Browser Console returns this message: "Component returned failure code: 0x805e0007 [nsIWebNavigation.loadURIWithOptions]". BC indicates that it comes from https://dxr.mozilla.org/mozilla-central/source/toolkit/content/browser-child.js#316.

After some conversation with Mike Conley, we could confirm that error code comes from here: http://searchfox.org/mozilla-central/source/docshell/base/nsDocShell.cpp#9693.

Expected results:

I should be able to navigate normally.

PS: if you disable e10s, it is possible to navigate normally on the tab.
