Try exiting Firefox via the 3-bar menu button -> Exit. I've found that using the close button in Firefox instead of the Exit button will leave a ghost Firefox in your Task Manager. Since I've started going the latter route, I haven't had this issue.

How do I add close button to this?

Sometimes when FF is closing, not all of it shuts down properly.
