No, it doesn't. Unlike iOS, which is a full operating system, Firefox OS is basically a web browser. The apps are all web-based apps. Firefox isn't just one app of many that runs on the OS (as Safari is on iOS), Firefox IS the OS and all the apps running on it are Javascript/HTML/CSS. So, while Google could probably build Chrome out of Javascript and run it atop the Firefox OS engine, it wouldn't make sense to do so. Asking if you can is basically like asking if you can create Chrome as a Firefox extension on Windows. Sure, you probably could with enough effort, but it would be a bit pointless in terms of functionality, speed, practicality, etc. Additionally, this is a bit of a straw man that Apple fans trot out when people accuse Apple of being anti-competitive with iOS. It's not an equivalent situation. An equivalent situation would be if Google forbid other browser engines from running on Android. But, they don't. So, we have a nice competitive browser ecosystem on Android with solid browsers like Firefox that I use every day.
