When I was visiting a web page using Firefox privacy mode, I found that its status was the same as that of non-privacy mode. I don't know if I started the privacy tour mode correctly, which made me wonder. I often need to close the current window and restart the Firefox privacy mode, so I hope that the window in the privacy tour mode will always display a mask. This will remind the user that you are currently in the privacy tour window. I support Mozilla's values and I want to make Firefox better
