As it stands now, Google Chrome is a pretty nice browser (see my review), but the Java plug-in doesn’t currently work. However, there’s an easy fix.
Google Chrome requires Java 6, update 10, which is currently in Beta. Please see this page in the Chrome Help Center.
If you want, you can also skip straight to the appropriate download on the Java site.
Once installed, you should have access to all the Java games and utilities that your heart desires!
Hope this helps someone.
