Godzilla in the context of Toho

The project that became Firefox today began as an experimental branch of the Mozilla Suite called m/b (or mozilla/browser). Firefox retains the cross-platform nature of the original Mozilla browser, using the XUL user interface markup language. The use of XUL made it possible to extend the browser's capabilities through the use of extensions and themes. The development and installation processes of these add-ons raised security concerns, and with the release of Firefox 0.9, the Mozilla Foundation opened a Mozilla Update website containing "approved" themes and extensions. The use of XUL sets Firefox apart from other browsers, including other projects based on Mozilla's Gecko layout engine and most other browsers, which use interfaces native to their respective platforms (Galeon and Epiphany use GTK+, K-Meleon uses MFC, and Camino uses Cocoa). Many of these projects started before Firefox, and may have served as inspiration.

Hyatt, Ross, Hewitt and Chanial developed their browser to combat the perceived software bloat of the Mozilla Suite (codenamed, internally referred to, and continued by the community as SeaMonkey), which integrated features such as IRC, mail, news, and WYSIWYG HTML editing into one internet suite. After it was sufficiently developed, binaries for public testing appeared in September 2002 under the name Phoenix. This name carried the implication of the mythical firebird that rose triumphantly from the ashes of its dead predecessor, in this case Netscape Navigator which lost the "First browser war" to Microsoft's Internet Explorer. The name Mozilla began as the internal codename for the original 1994 Netscape Navigator browser aiming to displace NCSA Mosaic as the world's most popular web browser. The name for this would-be "Mosaic killer" was meant to evoke the building-crushing Godzilla.

Godzilla (Japanese: ゴジラ, Hepburn: Gojira) is a Japanese giant monster, or kaiju, franchise centering on the titular character, a prehistoric reptilian monster awakened and powered by nuclear radiation. The films series are recognized by the Guinness World Records as the "longest continuously running film series", having been in ongoing production since 1954, with several hiatuses of varying lengths. There are 38 Godzilla films: 33 Japanese films produced and distributed by Toho Co., Ltd., and five American films; one by TriStar Pictures and four films (part of the Monsterverse franchise) by Legendary Pictures.

The original film, Godzilla, was directed by and co-written by Ishirō Honda and released by Toho in 1954. It became an influential classic of the genre. It featured political and social undertones relevant to Japan at the time. The 1954 film and its special effects director Eiji Tsuburaya are largely credited for establishing the template for tokusatsu, a technique of practical special effects filmmaking that would become essential in Japan's film industry since the release of Godzilla (1954). For its North American release, the film was localized in 1956 as Godzilla, King of the Monsters! and featured new footage with Raymond Burr edited together with the original Japanese footage.

King Kong, also referred to simply as Kong, is a fictional giant monster, or kaiju, resembling a gorilla, who has appeared in various media since 1933. The character has become an international pop culture icon, appearing in several movies, comics, videogames and television series, as well as repeatedly crossing over with the Godzilla franchise. Kong has been dubbed the King of the Beasts.

His first appearance was in the novelization of the 1933 film King Kong from RKO Pictures, with the film premiering a little over two months later. A sequel quickly followed that same year with The Son of Kong, featuring Little Kong. The Japanese film company Toho later produced King Kong vs. Godzilla (1962), featuring a giant Kong battling Toho's Godzilla, and King Kong Escapes (1967), a film loosely based on Rankin/Bass' The King Kong Show (1966–1969). In 1976, Dino De Laurentiis produced a modern remake of the original film directed by John Guillermin. A sequel, King Kong Lives, followed a decade later featuring a Lady Kong. Another remake of the original, set in 1933, was released in 2005 by filmmaker Peter Jackson.
