I remain unconvinced that a Blink-WebKit duopoly would be a better situation than what we have now. For one, Apple has more than enough money to fund WebKit development, and I am not sure the sudden addition of the Firefox team would be welcomed or beneficial there. And while Gecko and WebKit share many of the same goals, they diverge in parts of the browser I consider critically important, such as extensibility. Even if Firefox has low market share I consider their contribution to the browser space to be much more than their usage share would imply.
