Can I go back to the old Firefox?

Method 1: Download older versions directly from Mozilla

Why did Firefox close by itself?

Firefox may close or crash without warning for any of several reasons. If the browser or a plug-in is out-of-date, a simple update may resolve the crashing issue. At times, the problem can result from a needed update of your computer's operating system.
