Every instance of a nonnative UI framework ends up being merely tolerated by users. They don't love it because they can tell something is slightly off from native UI. Whether it is a less-than snappy menu dropdown, or imitation fonts, it ends up feeling cheap. So, stop aiming so low and make something that users will love - right to the smallest detail. I'm not surprised Mozilla took this route, though. They are more focused on openness and freedom on the web, which are also admirable goals.
