Lately, I have been getting a pop-up error when I start and close Firefox. The error reads: "XULRunner Could not determine any profile running in backgroundtask mode!"

I have found posts such as this one: https://support.mozilla.org/en-US/questions/1398228 and other posts suggesting to disable the scheduled task in Windows Task Scheduler, but none of the solutions have worked thus far. Anyone know of any other solutions?
