Every six weeks, a new major Firefox release hits the streets, and it’s soon available in the Ubuntu repositories, but thanks to Canonical’s Snappy technologies, users now have access to the latest ESR versions of Firefox too, which are mostly intended for the company’s enterprise partners who want long-term supported Firefox release. The Snap versions of the Firefox ESR web browser are created by the Mozilla Release Engineering and will be supported for at least one year. They are perfect for those using the LTS (Long Term Support) version of Ubuntu Linux, as Mozilla is selective about the patches that are pushed into the ESR version of Firefox.
