Unlike Firefox on the Release channel, Nightly sends by default anonymized usage statistics, called Telemetry which helps us improve Firefox and track regressions on a daily basis. If you are a power-user, that you want to have access to features in developments months or years before they become mainstream, have tolerance for occasional functional regressions and are looking for an easy way to help Mozilla and Firefox development, you should use Nightly (ideally as your main browser but you can also use it alongside Firefox on the release channel or another browser). Of course, Nightly does not have the polish, quality and stability of the Release channel as this is a work in progress but we are doing our best through automation, QA and community to provide you the best nightly builds possible. This development process used to ship a new version of Firefox every 4 weeks is called the Train Model. Once this code matures, it is merged into the Beta stabilization repository where that code will be polished until we reach a level of quality that allows us to ship a new final version of Firefox to hundreds of millions of people. 9.3.3 Is there a Nightly repository for my distro?Įvery day, Mozilla developers write code that is merged into a common code repository (mozilla-central) and every day that code is compiled so as to create a pre-release version of Firefox based on this code for testing purposes, this is what we call a Nightly build.9.3.1 Why is Nightly provided as a tar.bz2 archive?
