If you can recall how the program got installed without your approval, please let us know. You should always have control over software installed on your computer. ---- If you share your computer with someone else, it's possible they installed it. You can always use Internet Explorer by starting it up directly using its "e" program icon. If your desktop shortcuts to web pages or links in emails launch Firefox instead of IE, you can change that by letting IE make itself the default browser. ---- If there's no reason to keep Firefox, you can uninstall it using the Windows control panel: start orb > Control Panel > Programs and Features Look for "Mozilla Firefox"
