I have been using Netscape/Mozilla, in terms of heritage, ideology, and codebase, for almost a third of a century now.
I was there 30 years ago using NCSA Mosaic when it was first released for the VMS Vax system. The only break of any kind I had was with Opera as a secondary browser in the few short years between Netscape 4 and Phoenix (original Firefox). And I was still using Netscape 6, just not exclusively.
They can tear Mozilla (or any one of its forked variants) out of my cold, dead hands.
