I keep getting the message that Firefox is running in the background and I cannot load another page. I have to restart my computer to get Firefox back to operating normally. I have everything closed down as far as I can tell. But when I click on the Icon it will not start another page. It just keeps telling me to shut down all browser windows and that Firefox is running in the background. I even go to ctrl/alt/delete and look at the tasks running. Nothing! It is happening a lot more often now and I hate to use Internet Explorer. I have depended a lot more on Mozilla in the past few years now and I like it. This is driving me nuts. Please help. Thank You
