I’ve tinkered with the Chrome Web Store and decided it was only useful, if I were say running Chrome OS. I don’t see the point of installing a webpage as a application… Which I’ve been able to do for years not just making shortcuts, or pinning sites to the taskbar, and I don’t even do that.

Pushing cloud computing and Mozilla is basically competing with Google Chrome.

Mainly benefits the developers as they can make one app that will work on any device with a web browser but users can benefit from easy to run apps that also scale with the device they use. So they can often use it on their phones and then switch to their laptop or desktop and continue using the same app.

Think of it as the alternative solution to an all in one OS like Windows 8 is trying to be.

Capabilities, performance, and features will just be limited like all mobile and web apps usually are… but the idea is basically setting the ground work for when cloud computing gets more practical and we can start running more powerful applications online… much like we’re already doing with gaming with services like OnLive.

that’s exactly why the Mozilla Marketplace exists: we believe you should install (or buy) an app once then be able to run it on all of your HTML5 platforms. An app you buy from the marketplace isn’t limited to Firefox, it works on any modern HTML5 environment including Chrome and IE9. You get a rich experience by running an app in our native bootstrap for Mac, Windows, and Linux. You also get a rich experience in Boot To Gecko (an upcoming mobile OS written in HTML5/JS). Web browser bookmarks can’t do that and Chrome OS isn’t trying to do that.
