Anyway, I'm committed to improving the Open Web, even at the expense of Firefox market share if it comes to it (but we are still growing, and Firefox still has the second-place leverage to improve the Web quickly). If we should fail and just make a fancier browser whose nascent standards are not adopted by IE, at least we tried. The alternative is to renounce innovation and let the proprietary rich clients move the Closed Web forward. That might be convenient for some (big company) developers. It's not in the interest of the larger developer community, or of the public, in my book.
