Using: Firefox 80.0.1 and then 81.0 (64-bit) [It updated during the test]
Latest Windows 10 build
Screenshot Captor: v4.36.2 (Licensed)Firefox Window: Focused
Attempted to capture screen using both Keyboard Shortcuts, Quick Capture Bar and from within the Screenshot Captor Main Window.
All capture methods attempted (Minus Full-Screen DirectX)

Can anybody else give this a try to see if we can help mouser get to the bottom of it?
