Mozilla has set an aggressive schedule for the next version of Firefox, slating the release of Firefox 5 for June 21.

If it meets that schedule, Mozilla could crank out Firefox 6 just two months later.

Mozilla has shifted to a faster-paced development cycle where it adds new features as it goes to a series of versions -- dubbed nightly, aurora, beta and Firefox -- each of which feeds into the next-most-stable build until a polished edition is released.

The change is a major shift for the open-source company, which has been locked into a much longer schedule. Firefox 4, for example, was in development for over a year, while Firefox 3.6 took about the same amount of time to finish.
