Yes, another Web Store, Mozilla has already launched the first stable version of its Open Web Apps. This is the first milestone of Mozilla Web Application project for Web Apps that can run on any device and operating system, in which Google Chrome it is also included, and their way of distribution is pretty flexible. Without a doubt Mozilla will have its own Web Store side by side from Firefox Add-ons distribution, but what is also interesting is that developers will be able to run their own Web Store, or they can just simply offer their Web Apps on their own.

For users, you will need to first install an add-on (Firefox or Chrome), then simply visit the Mozilla’s Demo Apps page and start trying the Web Apps that are ready right now!

For developers, this is a big first step forward toward the future of Web Apps, this release brings a great tutorial for beginners to start creating Web Apps and stores, a stable OWA Application Manifest to safely start building apps, and there is also a stable API for JavaScript that it is very useful when interacting with the Web browser.
