Mozilla Foundation has released a new alpha build of Firefox Aurora version 5.0a2, is designed to represent the first public glimpse of future versions of Firefox in an early, unstable form.
The release of Aurora coincides with Mozilla's announcement of its new rapid release development cycle, which brings it into line with rival browsers like Google's Chrome. According to Mozilla, Firefox 5, Firefox 6 and Firefox 7 will all offered to end users in 2011.
Each version of Firefox, starting with version 5, will spend six weeks in development under the Aurora banner. Once a release has migrated from Aurora to Firefox Beta, Aurora will move on to the next version number, synchronizing with the latest nightly build at that point in time.
According to the plan, Firefox 5 will move into Beta on May 17, after spending just five weeks in Aurora. Similarly, FF5 will only spend five weeks in Beta and will be offered to public on June 21st, the day when the version is scheduled to graduate from the Beta to the Release Channel.
Under normal conditions, future Firefox releases will cook for as much as six week in each of the four development Channels, Nightly, Aurora and Beta before being considered ready for release.
Firefox 6 will move into Aurora on May 24, and into Beta on July 4. And, will be migrated to the Release Channel on August 16, 2011.
Firefox 7 will enter Aurora on July 4, Beta on August 16, and Release Channel on September 27.
At the time of Firefox 7's release later this year, Firefox 8 would already be in Beta while the first Firefox 9 Aurora release would be available to early adopters.
