[Bug 1732253] [NEW] Firefox 58 doesn't start the second time: entity is not defined

[Jérémy VIGNELLES]

Public bug reported:

This is a transfer of
https://bugzilla.mozilla.org/show_bug.cgi?id=1416851, reported on the
wrong platform. I'm on linux mint, so ubuntu-bug didn't work, and I
didn't find how to use apport correctly. Since yesterday, I updated my
firefox package but without luck.

Steps to reproduce:

OS: Linux mint 18.1 cinnamon 64 bits
Installed firefox from PPA: (from my apt sources lists:)
deb http://ppa.launchpad.net/ubuntu-mozilla-daily/firefox-aurora/ubuntu xenial main
deb-src http://ppa.launchpad.net/ubuntu-mozilla-daily/firefox-aurora/ubuntu xenial main

Firefox version 58.0~b3+build2-0ubuntu0.16.04.1

Steps I've done:
-Launched firefox
-Enjoyed it
-Close it
-Launch firefox again later, (after a reboot for example)
-See the awful message
-Tried -safe-mode without luck
-Downgrade to 56
-Firefox is starting again
-Upgrade again
-First run is ok, second is broken.


Actual results:

See the attached screenshot.
For non-french speakers, here is my translation:

XML analysis error : Entity is not defined
Location : chrome://browser/content/browser.xul
Line 381, Column 7

<menuitem...


Expected results:

Awesome firefox launching

I'm available if more info is needed :)
