If I press X (close) button and multiple tabs are opened, I have a warning. This is fine. But if there is only one tab, the window closes with no warning.
The problem is I have sometime many windows of various programs opened, stacked on each other, and it happens that, when I want to close a windows other than Firefox, I click on the Firefox close X button and I have to relog in everything I was logged in.
I would like a simple check box to confirm the closing of the Firefox window even if there is only one tab opened.
Many thanks!
