Flaki @sublevel have you thought about posting the app on the Firefox Marketplace (as a so-called "Hosted" app?) developer.mozilla.... - sublevel seems to be a nice fit with mozilla's values, even. ;)

💬 Subreply Sublevel embraces only web standards. It works on any browser on any device. Supporting Firefox OS manifest is not a standard, it's just as wrong as META="apple-mobile-web-app-capable" for iOS.
