Mozilla Firefox crash Ubuntu 16.04.2 desktop i386 iso

Asked by Lester S

Hello, is there a fix yet or still in progress? I upgraded through classic menu indicator from 16.04.1, when trying to open firefox, mozilla crash reporter displays, restart does not work. If available, I'd like to copy/paste to document, open and paste through terminal on broke pc to fix the problem.
Thanks

Please provide the output of the following diagnostic commands:

uname -a
lsb_release -crid
apt-cache policy firefox

Such crashes can be caused by faulty personal settings.
If you log in as guest, does firefox work as expected, or do you get the same crash?

Is there any additional information available from the Mozilla crash reporter?

You might try reinstalling firefox (with the command sudo apt-get install --reinstall firefox)

Remark: to get rid of the warning from apt-cache you could delete the offending file
sudo rm /etc/apt/apt.conf.d/50unattended-upgrades.ucf-dist'

Just the Mozilla crash reporter, no additional info.
Ran sudo apt-get install --reinstall firefox, rebooted, then removed firefox web browser from Ubuntu Software Center, rebooted, installed from Ubuntu Software Center, still get Mozilla crash reporter.
Also ran:
lessho@AMD:~$ sudo rm /etc/apt/apt.conf.d/50unattended-upgrades.ufc-dist
[sudo] password for lessho:
rm: cannot remove '/etc/apt/apt.conf.d/50unattended-upgrades.ufc-dist': No such file or directory

Reinstalled Ubuntu 14.04.5 desktop i386 iso and still had problems, couldn't open Thunderbird mail this time either. Reinstalled 16.04.2, no change. Decided to Try Ubuntu from external media and Firefox opened. Figured it must be my PC, only thing I could think of was reset my BIOS back to default settings, fixed the problems, things back to normal and working, the 50unattended-upgrades were gone before that also.
Thanks for the help.
