Until Mozilla fixes Firefox's security flaws I'm using either Safari, Opera, or Camino (none of which run the new version of Yahoo Mail so it's back to Yahoo Mail Classic--IE is not supported for Macs), though since Camino is also a Mozilla product maybe I should avoid it too. The most recent versions of Safari won't run on Panther (which came installed on my 3 year old powerbook; I never upgraded to Tiger), so maybe I should use Opera.
