Re: How do I make Firefox stop asking if I am sure I want to close tabs?
Of course I know about those settings. The problem was that I did not check the box for warning me when tabs are closed, but I was always warned anyway. I found another answer that involves going into about:config and changing a true value to false. I'm sorry, but I cannot remember if it came from this forum or another. I made the change suggested and the problem is solved, no matter that box is checked or not.
