    Sometimes when I open Firefox 84 I get a box with this message saying already running but must be closed so new one can start. If I look at Control Panel>Programs and Features I see only ONE Firefox. What is causing this message and what can I do? Not a real problem but an annoyance.
    Happened just now when Firefox set as default browser and I clicked to open g mail.

    You opened Firefox more than once. I see this when users are impatient and/or computers are slow. They click to get their Firefox or other application open. Then they don't see immediate results so they try to do it again. The first instance hasn't completed opening and the user tried starting it again. If you go to the Task Manager, you can see the processes running.

    Thanks for the explanation Tony. That is very likely what I did.
