Try Firefox 6.0 and 7.0 soon

Christian Legnitto, release manager at Mozilla, has published some details on development of the upcoming version of Firefox browser. According to information specified we can conclude that Mozilla community has indeed boosted the launch rates for next versions of its browser, while first test builds of Firefox 6.0 and Firefox 7.0 can be already seen in mid April and mid May respectively.

In addition to Central, Beta and Release channels, Mozilla has introduced a new repository — Aurora, which will be firstly used during development process of the next big update — Firefox 5.0 — a successor to recently introduced Firefox 4.0.
Legnitto adds:

Firefox 5 will be slightly different from future releases due to the development overlap (or lack thereof) with Firefox 4. Rather than 6 weeks for mozilla-central, mozilla-aurora, and mozilla-beta we instead have 3 weeks for development on mozilla-central, 5 weeks to converge and stabilize on mozilla-aurora, and 5 weeks to validate on mozilla-beta.

Firefox 5.0 can debut in June-July 2011 while the following Firefox 6.0 and Firefox 7.0, according to leaked roadmaps, should appear by the end of this year.
