I'm not having this. I've recently switched back to Firefox from having used Chrome & Opera in the past. Yes, the domain guessing is annoying, but you can configure it. As for performance issues, Firefox has made great strides over the last few releases. The best features of Firefox in my opinion are; - Made by a impartial vendor - The best selection of addons - Release cycle in tune with the internet and on par with Chrome - Open source - Familiarity - Speed, still runs rings around IE, and good enough.
