A side-comment
I 'helped' someone install Netscape 8.0 last evening -- that is, I watched while it installed itself -- after trying for weeks to convince the person to go with Firefox instead...
Netscape's a Mozilla product, too, y'know. And now it has tabbed browsing.
When it opens up, down in the lower-left corner is a pair of buttons. One has a variation on the infamous Microsux "e"; the other has an official Firefox logo. They're for choosing how to view the active tab (or page).
Looks to me like even Mozilla acknowledges that their stand-alone browser is better than their integrated package.
