About Chrome, well, I've had to quit using it. If you'll look at all the bug reports I've filed, you'll see there are several problems when trying to use it with Yahoo Mail. It also doesn't render several websites properly, and I've reported those as well. And lately it keeps crashing. I notice this when it takes two attempts to close every tab, and then finally I just have to "force quit" Chrome.
Chrome definitely seems faster than Firefox and other browsers, but once I realized I was "living with" all these little problems just for the little speed increase, well, it just doesn't seem worth it.
