I believe you posted this question a few days ago. And I told you that if Firefox is causing all these problems, then you don't need Firefox. Can you not close the browser before attempting to shut down? I use Firefox every day and it causes me no problems. Once in a while, it will open up slow. But closing it is no problem. Does your other browser(s) cause this? If not, then it is a problem with Firefox. Have you tried disabling add ons on your browser? That's a starting point, disabling them all at first, then enabling them, one at a time. Then when you come to the one that gives you trouble, remove it entirely. You need to go to this site's control panel and add some specs of your computer so that we can better help you. The only thing we know about you is your screen name and that you use Firefox. It could be other things as well as Firefox that is causing your problems. The last time you posted, I suggested to you to try Opera, or any other browser of your choice. If you are still having problems, then it's most likely a hardware issue. How much RAM (memory) do you have? As I told you before, if it is indeed Firefox that's causing this problem, then you don't need Firefox. And if you keep on shutting down your computer this way, you'll soon need a new one. Give us some more info so that we can help you. Your problem may be somewhere in the details.
