One thing that bothers me is the fact that Wordpress is not dropping support for FF or Chrome just because the automatic upgrade feature.

You could be running latest Chrome browser in XP, why does Microsoft doesn't do something about this? We all know.

To be honest I only used IE once to download Chrome, but I still keep it as Chrome doesn't work with Java and sometimes I need Java for goberment features that requires Java enabled.

I barely test my sites on IE as well... Just saying.
