An open source Web browser designed for standards compliance, performance, and portability. It was the original version of the Netscape browser and now Firefox is Mozilla's next-generation Web browser. Some people claim that the name is a cross of Mosaic and Godzilla (as in, "the Mosaic killer"), since Mosaic was the number one Web browser at the time Netscape began developing its product.
Mozilla is still used by many Web developers, and it appears in server log files that identify users' browsers. Artist Dave Titus created the Mozilla mascot (a smiling dragon). It was used in Netscape's early years but has mostly been replaced by their nautical "N" icon (however, Mozilla the dragon still appears from time to time).
