Product development perplexes me these days. Alphas used to be internal-only builds that were made available to developers, employees and generally within a company. The next stage would be an early beta that would go out to a limited number of people who were aware that it was still and early build and shouldn't used on a production machine. These days, we're seeing alphas released to the public for 'internal testing' and, slightly more bizarre, multiple alphas before we even reach first beta.
Mozilla Firefox 3.0 alpha 6 is the sixth very early preview of the forthcoming major browser from Mozilla. This release contains a major re-write of the text rendering code and various other fixes and minor changes. Bear in mind that this still isn't designed for production use and should be used as preview technology only.
