Netscape 4.8

I almost forgot about Netscape 4.8, also available at system7today.com.
It's supposed to be faster than 4.78, it's the latest to run under
System 7.6.1, and it includes the whole Communicator suite (browser,
e-mail/newsgroups and Web design with Composer).

While 4.78 is dog-slow -- even though it's supposed to be optimized for
PowerPC, it's the only version of Netscape that still sort of works
(especially on e-mail and for Web browsing). A speed-up of any sort
would be most appreciated.
