Huh. Apparently the new Netscape 4.76 release for Mac is quite significant... a big feature is the ability to use the MRJ for Java, increasing compatibility with applets.

I wonder though, would that be at the expense of the Java/JavaScript bridge?

Netscape was the only browser that supported JavaScript scripting of Java applets on the Mac... a strategic move by Microsoft to slow down Java, I'm sure. I hope it still supports it.
