Despite the fact that Firefox 15 is still in beta, Mozilla is still working on integrating web apps in the next Firefox 16 version. Mozilla introduced compatibility with web apps in the Firefox 16 alpha version.
The new web browser will also include Firefox OS compatibility. Firefox OS mobile operating system will arrive in 2013. Firefox 16 includes multiple improvements, from Voice-over interactions on Mac to functionality improvements for reading PDF files. Mozilla is working on web apps for both Firefox 16 and Firefox OS, the mobile operating system which will arrive at the beginning of next year and the same experience is being offered regardless of the platform used by users. By the end of the year Mozilla will also open Mozilla Marketplace, where users can download applications. The new version will arrive in August.
