I'm disappointed by how many people cling to Chrome/Chromium under the justification that they don't like where Mozilla is going. If you can't tolerate Firefox because of Mozilla's problems, how can you possibly stomach Chrome/Chromium with Google at the wheel?
I believe browser diversity is healthy for the world wide web. I don't want Firefox to become dominant either, but right now there is a short supply of browsers which are independent from Chromium. I don't want the W3C to be replaced by the Chromium Project.
I believe Firefox is a good enough browser to go toe-to-toe with Chrome. It and it's developer are not without problems. However, at this point I'd use Firefox even if Mozilla was just as bad as Google because I think the diversity is worth it.
