We all know that Windows XP was the Microsofts most widely used and well-known operating system.
However, recently, Mozilla announced that Firefox will no longer be supported on Windows XP and Windows Vista.
Several software companies are abandoning this version and Mozilla was the latest to declare this intention.

From mid-2017, Firefox will no longer be supported on Windows XP and Windows Vista.
Microsoft itself no longer supports this system and has therefore left it exposed to emerging security issues.
But Mozilla does not want to remove Firefox from these two systems completely.

Firefox will continue to work on Windows XP and Windows Vista.
