I recently purchased a new computer with Windows 8 on it. I promptly downloaded Mozilla uses my web browser. Everything works fine for a couple of weeks and then today I could not bring the browser up on the page. It seems to launch when I click on the icon on the desktop. But when I click on the icon on the toolbar it shows the small image of the browser but when I click on that image it won't show up on the page or the screen. When I go to push the icon on the desktop again it appears to launch a second browser and two browsers are shown when I push the Mozilla icon on the toolbar at the bottom. I can close the browser's over the one I want to close and right clicking and close. I have deleted Mozilla from my computer and reinstalled it from the website and continue to have the same problem. It appears something has changed someplace because as I stated it worked fine from the beginning. all my other programs including Windows Explorer continue to work fine. Any help you can give me I would appreciate.Thank you
