For the download-obsessed, unquenchable binary junky, there may be nothing more tantalizing than the avant gard, freshly squeezed, and oozing-with-promise alpha version. Two steps from actual stable release and fresh from the programmer's build tool, alpha versions of software tend to be like Swiss cheese--very, very delicious but with a few holes.

Such is the case with the alpha version of Firefox 2.0, the latest iteration of the venerable open source web browser, which was uploaded today for Mac, Windows, and Linux. You can grab it from the official Firefox repository, if you think you can swallow an alpha version.  Of course, if you're just curious about trying Firefox and you'd prefer a stable release, the current release version is 1.5. You can get that from the official Firefox site.
