Originally, there were only 4 release channels for Firefox, namely Beta, Stable, Aurora, and Nightly. However, only 3 are available on Android via the Play Store. Such would include Firefox, Firefox Aurora, and Firefox Beta.
However, it can be recalled that Mozilla has made an earlier promise to swap the Aurora to its Nightly build. Although the app would be a bit different, Play Store listing would remain the same.
Mozilla will also deliver to the users the Nightly build of this version of the browser, even as the package is still org.mozilla.fennec_aurora. According to the company, Aurora did have a tiny user base, so it decided to streamline the releases. Although the Nightly builds are the quickest to get updates, they are also the least stable.
The availability of Nightly releases on the Mozilla website has already been around for a while now. This makes the availability of such releases not entirely a new process. Nevertheless, it has become more accessible by placing such releases on the Play Store. According to Mozilla, this would be more famous than Aurora. However, this change could not affect Stable and Beta releases.
This feature works as a development channel for the new releases of Mozilla Firefox. This was designed to display the more experimental builds of Firefox. According to the company, the Nightly channel would allow users to try the latest innovations in an unstable environment. This would also allow users to provide feedbacks on performances and features in order to determine the final release.
The next time you visit the Play Store, you wouldn’t be able to see Firefox Aurora, but Firefox Nightly. This transition should be favorable because it would streamline the releases in order to get new features to the users without further delays.
