    Upon installation, Firefox will not be your default browser, which you'll be notified about. That means that when you open a link in your mail application, an Internet shortcut, or HTML document, it will not open in Firefox. If you want Firefox to do those things, click Use Firefox as my default browser. If you're just trying out Firefox or simply do not wish to set Firefox as your default browser, click Not now.
