Mozilla Roadmap
Mozilla's browser development team (Netscape Communicator 5.0) chose the GTK+ library as the main one for development under XWindow, thereby replacing the commercial Motif. The GTK+ library was created during the development of the GIMP graphics editor and is now used in the GNOME project (creating a free graphical environment for UNIX).
