why does ucrtbase.dll cause a fault in pingsender.exe?
Firefox opens fine and works fine. When I close it I get error messages. Event Viewer says the faulting application path is C:\Program Files (x86)\Mozilla Firefox\pingsender.exe, and the faulting module path is C:\Program Files (x86)\Mozilla Firefox\ucrtbase.DLL. The same module is causing faults in other programs I use.

I don't know what that file does, or how it could be relevant to other programs. Could you try:
Clean Reinstall
This takes about 5 minutes. It's not about your settings, it's about making sure the program files are clean (no inconsistent or alien code files). As described below, this process does not disturb your existing settings. It's not essential to uninstall Firefox, but you can if you like, saying No to any request about removing personal data.
(A) Download a fresh installer for Firefox to a convenient location:
https://www.mozilla.org/firefox/all/
(B) Exit out of Firefox (if applicable).
If you use Microsoft Office, please change your default browser to Internet Explorer temporarily before the next step.
(C) Using Windows Explorer/My Computer (hold down the Windows key and press E to launch it), right-click > rename the program folder as follows (you might have one or both):
C:\Program Files (x86)\Mozilla Firefox =to=> C:\Program Files (x86)\OldFirefox
C:\Program Files\Mozilla Firefox =to=> C:\Program Files\OldFirefox
(D) Run the installer you downloaded in step (A). It should automatically connect to your existing settings.
Any improvement at your next startup and shutdown?
Note that the PingSender is controlled by this pref.
