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. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

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; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ 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.

Hi Fred, thanks for checking in. No good though. I've tried clean install a few times at this point. :\

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Start your Computer in safe mode with network support. Then start Firefox. Try Safe websites. Is the problem still there?

Hi Fred,

Neither of those worked. I can't get into safe mode b/c the crash happens immediately at startup of the app. Safe mode of the OS didn't change that either.

Cheers,

If at all possible update video card drivers.

Note that there might be issues with Mac High Sierra (10.13) that haven't been resolved.

Did you do a clean (re)install and drag the Firefox to the Trash?

Try to create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Hi Cor-el and Pkshadow,

After a fresh install of FF, the crash does not generate any crash report except, I assume, the native Macos one, but I believe that one goes to Apple.

There is no 'Submitted' folder, see attached.

As to the drivers, I can only do that after I update to Macos 10.13.2 (currently I'm on 10.13.1, but can't update until the weekend) as they're version-locked for some reason.

Thanks again,

Updated to 10.13.2, and updated gfx drivers, but no change. :\

Hello - thanks for your reply. I cannot even get into the app. No safe mode, no profile, nothing. This is a fresh install w/o any previous profile.

When I try to start it w/ the profile manager from Terminal I get this:
