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 stabilization repositories (Beta and Dev Edition) 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.
