Mozilla is planning to release the next alpha versions of their open source web browser on a monthly basis. Firefox 3, the current alphas for which are codenamed Gran Paradiso, is Mozilla's next major version milestone of its most popular application that a growing number of users have embraced. Gran Paradiso is a developer release (not intended for day-to-day use) which employs Mozilla's next generation layout engine: Gecko 1.9. Alpha 4 was released at the end of April, Alpha 5 is scheduled for May and Alpha 6 is being aimed at June. Beta 1 is supposedly going to be released on July 31, 2007 – but I will be very surprised if it doesn't get pushed back.
