The name "Mozilla" was already in use at Netscape as the codename for Netscape Navigator 1.0. The term came from a combination of "Mosaic killer" (as Netscape wanted to displace NCSA Mosaic as the world's number one web browser) and Godzilla. Mozilla was the mascot of the now disbanded Netscape Communications Corporation. Mozilla takes the form of a green and purple cartoon lizard. Programmer Jamie Zawinski came up with the name during a meeting while working at the company. He was designed by Dave Titus in 1994.
