I've downloaded the latest update for Firefox, but it does not seem to load. I just upgraded to Snow Leopard also. When I go through the install for the upgrade it pauses at around 20 mgb and then rapidly goes through the rest, but does not have any confirmation that the install was successful. When I open up the browser it is still the same old version I was using, which says it is unprotected and I need to get the latest upgrade.
