We've had this up on the Firefox Marketplace for some time now and just haven't gotten around to mentioning it. Pretty much, Mozilla Firefox has an app store just like the Google Chrome Web Store and the reason it isn't built right into Firefox itself (only Firefox OS links directly to the store right now) is because there's still some stuff that Mozilla is working on. What those things are, we don't know as the marketplace works perfectly, but what we do know is that we've submitted an app of our own to the store and it's up now for anyone that is using an up to date copy of Firefox, Firefox Mobile or Firefox OS.

_{We also have an app for Google Chrome if that's your choice of browser.}
