arjay19 ►Any idea what the differences will be for the new Firefox? So far I'm happy with the one I always use, and I always seem to regret it when I update stuff.
From Wikipedia:
"One of the big changes in Firefox 3 is the implementation of Gecko 1.9, an updated layout engine. The new version fixes many bugs, improves standard compliance, and implements new web APIs.[62] In particular, it will make Firefox 3 the first official release of a Mozilla browser to pass the Acid2 test, a standards-compliance test for web-page rendering. It also gets a better score on the Acid3 test than Firefox 2.
There are regular XULRunner-based builds being generated daily, but Firefox 3 is very unlikely to use this delivery mechanism.[citation needed]
Some of the new features are defined in the WHATWG HTML 5 specification,[62] such as support for web-based protocol handlers, the native implementation of getElementsByClassName method, support for safe message-passing with postMessage, and support for offline web applications. Other new features include APNG support, and EXSLT support.[62]
A new internal memory allocator, jemalloc,[63] is used rather than the default libc one.[64]
Gecko 1.9 uses cairo as a graphics backend,[65] allowing for improved graphics performance and better consistency of look and feel on various operating systems. Because of cairo's lack of support for Windows 95, Windows 98, Windows Me and Windows NT (versions 4.0 and below), and because Microsoft ended support for Windows 98 and Windows Me on July 11, 2006, Firefox 3 will not run on those operating systems. Similarly, the Mac version of Firefox 3 will only run on Mac OS X 10.4 or higher,[66] but, unlike previous versions, will have a native Cocoa widget interface.[67]".

The only problem is that the previous version has to be uninstalled before installing the new version. In other words, is not a update is something completely different!! (Not as good as my own Browser, Doomzilla, though).
