You're talking about the change from Netscape Communicator 6+ to Firebird and eventually Firefox in ~2003. That was a positive change.
I'm talking about the the change from Navigator 4.x to the MAS-based buggy crashy slow XUL monstrosity in 1998-2000. That was a terrible change, it killed Netscape as a company, almost gave Microsoft complete control over the future of the Web, and ended up necessitating Firebird/Firefox.
