To clarify: My point is not that Firefox sucks, my point is that Firefox is great - better at handling the web than these new other web-browser engines will be for a long time, and yet it still hasn't broken the moat. It's not enough to make a great non-chrome web-browser - we already have one. It wouldn't make any difference toward that goal if we had 4 of them. What is needed to break the moat are users - and enough for website operators to care. This is what Apple/Safari has. This is what Firefox increasingly lacks. For and for that someone will have to do something other than make a great browser.
