Getting "mw.mobileFrontend is undefined". I'm not sure why this is happening and although desktop Firefox is not very important for us, this might be a signal that something is wrong with templates implementation and/or Resource Loader.
I seems that MFResourceLoaderModule doesn't support dependencies (adding 'dependencies' key has no effect), but mobile.beta.dependencies module depends on mobile.startup (specifically mf-application.js). It's possible that it works in other browsers just by coincidence (mobile.startup is loaded fast enough for mobile.beta.dependencies to work).
