Moving Firefox to a faster 4-week release cycle

The Mozilla blog has an announcementthat Firefox will be moving to 4-week release cycle, starting in 2020."Shorter release cycles provide greater flexibility to supportproduct planning and priority changes due to business or marketrequirements. With four-week cycles, we can be more agile and ship featuresfaster, while applying the same rigor and due diligence needed for ahigh-quality and stable release. Also, we put new features andimplementation of new Web APIs into the hands of developers morequickly." The Firefox ESR (Extended Support Release) release cadencewill remain the same.
