Lol, what? I've always used both Firefox and Chrome due to doing web Dev. It's a perfectly good browser. It's been my primary browser on mobile for years since Google started the creep of removing choice in how you interact with Chrome.
Basically they listed all the cool stuff mozilla is doing and then complained that they want Firefox bundled with plugins and to be customizable for power users.
I dunno, I'm really happy with it and I don't miss anything.
