This would be my last straw with Mozilla. I've been peeved about Chromium forks for ages, but if Firefox isn't going to even try to be a good alternative, neither should I.
I've stood in defense of Firefox for a really long time, it remains my primary browser. And my hope is that in light of the publicity about this travesty of an attempt, Mozilla will backtrack. But I'm sick of Firefox being absolutely unwilling to support the needs of their already niche userbase.
