The Mozilla Apps platform
Building Apps for the Web provides developers with full control over content, functionality and how Apps are distributed, including access to hundreds of millions of Firefox users through the Firefox Marketplace.
Using open Web standards and Mozilla-designed APIs, great app experiences can be delivered across multiple platforms, devices and operating systems — closing the gap between Web and native apps for the first time.
Firefox Marketplace
The Firefox Marketplace gives users the opportunity to find, try and buy Apps and content that matters most to them. This means exciting, useful and high-quality Apps relevant to local markets across all categories that users can use to get the most out of their daily lives.
Mozilla's global reach extends to hundreds of millions of Firefox users worldwide. Through intelligent Marketplace curation and effective use of Mozilla’s marketing channels, Mozilla can help developers can get their App into the hands of their target users around the world.
Before the public launch later this year, Mozilla will be opening the Marketplace for user testing. Take advantage of this by being one of the first App developers to build a user base. Submit your App to:
- Test your App with a committed group of early adopters.
- Build an early fan base and gain popularity.
- Target tech savvy consumers with your App.
