The Firefox devices will compete with phones using Google's Android and Microsoft's Windows platforms.

Spice said, "The Spice Fire One Mi-FX 1 is purely targeted to the nearly 90 percent of the feature phone users wanting to switch to smartphones. The device is aimed at the masses that are looking for a larger than life phone statement but are deterred due to price sensitivity."
