I use Chrome for most things. Started using it during the AC when it was the only one that let you play properly for a day or two and stuck with it. I get an annoying thing when I refresh or open a new page though that it doesn't always display first time and I have to refresh again, anyone know how to fix that?
I still use IE for facebook, twitter and hotmail though, I like to have that easily separated from my other stuff and I'm not a fan of FF for no logical reason
