The Free On-line Dictionary of Computing (30 December 2018):

Mozilla

    The open source web
   browser, designed for standards-compliance, performance, and
   portability, whose development is coordinated by the Mozilla
   Foundation.

   The Mozilla project started in March 1998 when Netscape
   Communications Corporation released the source code of
   Netscape Communicator.  The now abandoned version based on
   that code is referred to as "Mozilla Classic".  Since then,
   much has been rewritten, including the layout engine, the
   networking library, and the front-end.

   Mozilla 1.0 was finally released on 2002-06-05.  Much of the
   code was used to build Firefox.

   Although a lot of Mozilla code is under the original Netscape
   Public License, some parts of the code are under the Mozilla
   Public License or dual MPL/GPL.

   "Mozilla" was the original project code name for Netscape
   Navigator and, according to some of the documentation, the
   correct pronunciation of "Netscape".

   [Derived from "Mosaic killer/Godzilla"?]
