With a sudden decision, Mozilla decided to throw away Firefox Aurora which was one of Firefox’s development stages. The reason of this sudden decision was said to be making Firefox release channel more stable and simpler. Mozilla declared that it will close one of Firefox’s release channels, the Aurora channel. Of course, after this change, those who have been testing Firefox on Aurora will automatically move to the Beta channel.
According to the Mozilla, there were not much users in the Aurora channel, thus this decision will not have a huge impact on the users. Dave Camp , Firefox Engineering Director said in a statement that Aurora was not successful enough to afford their expectations as the first stabilization channel. Mozilla has been offering four different versions of Firefox which are Nightly, Aurora, Beta and Stable Builds. Each of these versions was more resolute than the previous one when they first used.
Dave Camp also stated that they started to use more modern processes in the broadcast train model and they believed they could deliver functionally richer and more stable products without the need for 6-8 weeks of Aurora. With this train approach, Mozilla has been adding new functionality to the least stable version of Developer. As the function is ready it is moved to Aurora. Then the maturing function is moved to Beta and Release. But, now Mozilla accepted that this system sometimes failed. They skipped the phases to shorten the time in some cases.
According to the FAQ, users on the Aurora release channel began to move to Beta Channel. It is stated by the company that the removal of the Aurora channel will not change the frequency of the release channel structures. In fact, Mozilla will be able to switch between new functions by 6-8 weeks faster than before, as Aurora is no longer available.
