I have Firefox set so it keeps every window I go to open, and I want to change this to keep only the current window open. I've looked in Preferences but can't see anything that will automatically shut down the window I'm leaving to open up a new one. Can someone help, please?
Also, while I'm here, I always click the box to remember my name and password when logging on to this Forum, but it never works, for I always have to key in both each time. Why is this?
