Updated to Quantum (66.0.3 64-bit) on Windows 10. Created a Shortcut on the Taskbar to the FF exe. Now every time I click the shortcut icon a new instance of FF appears, where as previously, only ever 1 instance ran.

I've set click for new tab not window etc, but nothings stopping another copy running. BTW The instance is related to the screen an not processes in the Task Manager :)

Any ideas please?

When you right click on the icon what options shows up? You should get a list of options of what to do.
