Firefox OS is now available in 24 countries on 12 smartphones from 13 operators, a result of their aggressive expansion in emerging markets. India, Bangladesh, Japan, El Salvador, Panama, Nicaragua, Guatemala, Argentina, Germany, and Poland are among the many nations that now have Firefox OS smartphones on the market. The web-technologies-based operating system is designed to run on phones with slower specs than the high powered phones common on Android and iOS. This has led to a focus on developing nations as Mozilla’s primary target.
