This crash is occurring at random times. Once it happened after trying to print a document, once it happened after logging out of a website. I ran a Windows SFC scan and ntdll.dll was not corrupt. PC is running Windows 7 Pro x64, Firefox is 56.0.2.

These logs were collected from my user's PC remotely, so I'm not able to click Automatically Add since the issue is not with my own computer. If you need any other information that I did not include here, please let me know.

Any help in getting this figured out is appreciated. Thank you.

Let’s do a full clean re-install;

Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86)

Mac: Open the "Applications" folder.

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux;

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. ++++++++++++++++++++++++++++ Do Not remove the profiles folder.

Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder if there is one.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. If all goes well, remove the OLD folders when you are done. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.
