I don't know if this has anything to do with the name change.....but, a few days ago, I ran ChimeraKnight, and I noticed that the change log had an entry that said, "Added a link to Chimera.org". I went to the site, and it's a developmental site for "a World Wide Web browser for UNIX-based machines running the X window system." I began thinking....maybe this site took legal action against Mozilla and Chimera (Navigator), and the Navigator developers added this link in order to please the people from Chimera.org. Maybe the Chimera.org people weren't pleased, and pressured for a name change.
Of course, this is just pure speculation.
What does everyone else think?
