Firefox has stopped working (on startup)

On my work laptop (Windows 10, 64-bit), I've been getting this error sporadically (but fairly often) when *starting* Firefox.

> Firefox has stopped working

It happens before I even open any webpage. My homepage is a static local HTML file, and I do not save tabs when closing Firefox.

The error popup has options to "Close the program" or "Debug the program". The latter requires Visual Studio or some other program to be installed, which my laptop doesn't have. So I'm not able to debug it (although I wouldn't know what to debug anyway). The popup seems to originate from Windows, not from Firefox, as I've found no trace of the crashes in the Firefox log files.

The error only started happening after the browser was upgraded from version 57.*.esr to 60.*.esr. I've completely uninstalled Firefox twice (manually removing any leftover files/folders) and reinstalled it, but the error still happens, even with no customizations made nor add-ons installed. The problem still happens using the latest released version on the ESR channel.

The problem does *not* happen when using the same version of portable Firefox.

I suspect the problem is related to either the antivirus (McAfee) on the machine, or some other corporately-installed software (policy-checking, automatic updates, etc.) which I can't uninstall.

I did not find any reports of other people online having this particular problem with the current ESR version of Firefox. So I'm posting this here, in case any one else does a search on it. But unfortunately, I still don't have a solution.

Update, 2019/03/09: A few weeks ago, the laptop was updated to a newer build/version of Windows 10. Since then, the problem hasn't happened anymore.
