The Mosaic browser, which initially worked in UNIX environments on X11, was the first to be extended. Because this browser soon NCSA prepared versions for Windows and Macintosh.
However, a little later it entered the market NavScape Navigator that quickly exceeded Mosaic’s capabilities and speed. This browser had the advantage of working in almost all UNIX, as well as in environments Windows.
Internet Explorer (formerly Spyglass Mosaic) was the late bet from Microsoft to enter the market and managed to oust the Netscape Navigator among Windows users. Due to browser integration with the operating system, reaching about 95% of the share of the market. Netscape Communications Corporation released the source code of its browser, thus the Mozilla project was born.
