Back OT, I haven't noticed any drastic changes in Firefox 3.0.3, except for certain sites not allowing the Java applet to load (ie -
http://www.achaea.com/nexus/play.php ), whereas others will ( ie - java.com ). It's very odd, but, beyond that, I've noticed a memory usage drop, compared to the original 3.0 release. :shrug:
I'm minimalist in my extensions, though, and only keep what I need.
