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 :) ** Affects: firefox (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Screenshot of what's happening on startup" https://bugs.launchpad.net/bugs/1732253/+attachment/5009035/+files/startup_screenshot.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1732253 Title: Firefox 58 doesn't start the second time: entity is not defined To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1732253/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
