We keep only the most current and major releases in the main page. This is the complete list of all Firefox strings that we have ever found or received - including those on the main page.
Phoenix is dead - long live Firebird. Firebird is dead - long live Firefox. Firebird/Phoenix has morph'd into Firefox. The Mozilla roadmap shows Firefox as the browser for the next generation of Mozilla. Essentially (if we can paraphrase a very big page) the mozilla design team are saying that they will develop a set of components (browser, mail client, editor (composer) and others) which will work well together but will have their own development priorities and timeframes, rather than the current monolithic Mozilla structure. The historic Phoenix and Firebird strings are still on the main page 'cos we like to remind 'em of their humble beginnings. Note: For Firefox 3 and perhaps after, Minefield will remain the development version and always have 'pre' in the string, whereas GranParadiso is the release leg and will not have 'pre' in the string - so there you go. Shiretoko named for the Japanese Peninsula and a UN world heritage site (aren't we the smart ones) seems to be the development release leg for 3.5 - replacing GranParadiso? While Namoroka (a unique nature reserve in northeastern Madagascar) seems to be the 3.6 development release leg.
The 'mobile Firefox' is being developed under the current codename of Fennec (a small noctunal fox found in the Sahara desert) - man, who comes up with these names. But don't worry they'll change the name 427 times before release. Multi-platform - Linux and Windows Mobile so far.
Don't forget the Mozilla SeaMonkey project about which which J. Reynolds writes:
The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as "Mozilla Application Suite". Whereas the main focus of the Mozilla Foundation is on Mozilla Firefox and Mozilla Thunderbird, our group of dedicated volunteers works to ensure that you can have "everything but the kitchen sink" and have it stable enough for corporate use.
Note: The seamonkey strings are under Mozilla.
Nathan Lineback supplied this reference to a bunch of screen shots showing the OS's to which Firefox (1.5 mostly) has been ported.
Windows FF users may want to check out palemoon which claims to be up to 25% faster than the moz port by optimizing the FF code base for Windows.
