Mozilla Firefox is a fully customizable web browser. You can customize its appearance, such as color and themes, to suit your tastes. One of the features that you can customize in Firefox is the default font. Most browsers default to Times New Roman. In case you get bored or just want to make things more vivid when surfing, you could change the default font.
