&gt; Right. And the choice of programming language isn&#x27;t.<p>The platform isn&#x27;t just the language.<p>&gt; Firefox OS was based on locally installed apps.<p>Then I have no idea what we&#x27;re talking about.<p>So the point of Firefox OS was supposed to be what, you make the UI using HTML and javascript but then it runs locally and exposes system call wrappers through javascript?<p>That&#x27;s not actually so bad of a concept, but then you have the opposite problem. Nothing that does anything you can&#x27;t do in a traditional web page is portable outside of Firefox OS so you have no user base to attract developers.<p>It seems like they&#x27;re trying to compete with <i>Android</i> when they should be trying to compete with <i>Java</i>. Make a runtime that runs the Firefox OS apps on Debian and Android and Windows. That would be interesting.
