Netscape 6 is the greatest non-event in Netscape history ever. I'll ignore it completely. The five first and last minutes I used it, it behaved like Mozilla M15. Mozilla M18 is more stable (I used it all day long without a crash, unless I visit stupid websites I shouldn't be visiting anyway) and I like it. It has even driven me away from lynx for quick consultations.
Free and totally unrequested-for plug: OpenProjects, #conectiva, enough said.
