chrome is the best in my opinion
and when working on drupal sites the best thing you can do is have 2 browsers open, one for admin, one for other users. you can see how it looks on 2 browsers at the same time as well.
unfortunately when working on mac i’m stuck w safari and firefox combo.
i hate the new safari. hated the old one too, but the new one is even more annoying. what browser doesn’t have favicons displayed on the tabs??? maybe its just my setup? but its unbelievably inconvenient.
