Thanks Foueddy-F who posted the links in Back Page News.
Beta 2 of Mozilla Firefox 2.0 has just appeared on the Mozilla FTP in the release folder, it"s safe to say that this is Beta 2 and not a pre-beta.
Firefox 2 provides the same clean, streamlined, interface as previous versions, with small improvements to make it easier to use. In addition, it includes improved security features and useful tools to make the Internet experience safer, faster, and better than ever before.
