Firefox fans, and browser junkies have an opportunity to get a jump on Tuesday's beta, as a public "release candidate" has been posted on the Mozilla FTP site. This nightly build is finally feature complete, although it's still not completely ready for mass consumption.
Firefox 2.0 include a horizontal scrolling capability for tabs, and an ability to close a tab directly from within the tab itself. The Options dialog has been reworked to include a horizontal, tabbed based interface, and numerous changes have been made under the hood.
This new version of Firefox also offers relief for early adopters of intel-based macintosh hardware. One tester on Digg was overjoyed, saying "Oh thank you lord, Firefox finally work correctly on my Mac Mini!"
You can download the Windows release candidate of Firefox 2.0 Beta 1 directly, along with Mac and Linux versions, but beware. It will overwrite your existing themes, and render existing extensions unusable. A "portable" version of Firefox 2.0 that will let you try without affecting your existing Firefox setup has also been made available.
