Firefox Quantum keeps asking me to close Firefox on external launch

more options

When launched directly from Explorer, Firefox Quantum (v62.0.3) works fine. But when launched indirectly, say via some other program sending a URL to the default browser (FF), FF launches first but then it always brings up a dialog box saying that I have to close FF first! When I click the dialog button to do that, the existing FF window is closed, then it re-launches with the requested URL.

I'm running 64-bit FF under64-bit Windows 10 Pro.

What's going on, and how can I fix this extremely annoying problem?

Thanks!

Added Info: Here is the text of the dialog pop-up in question:

"Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."
