I have FFx 27.0.1 running. When attempting to close FFx with only ONE window/Tab open, FFx warns me that I am about to close TWO windows/Tabs instead. Clearly there is only ONE open, yet the Browser reads TWO for some unknown reason. Is there something wrong with FFx? I have searched my Settings & everything looks just fine. Does this indicate something wrong on my end? or is FFx acting up? Software conflict or what? Any ideas?

Thanks ahead of time...

This could indicate that you have a second tab group. If you press Ctrl+Shift+e to display the tab groups list, do you have two boxes, each with one tab? If so, try dragging the second tab into the first box, then click that box to return to normal display.

By the way, some users have reported a hidden tab in the past couple of weeks, perhaps related to an add-on. If you discover any pattern with the hidden tab, could you indicate what it is?
