Firefox Extended Service Release (ESR) is available for those who require consistency in the UI for a longer term.
http://www.mozilla.org/en-US/firefox/organizations/.
Major version releases are only every 12 months. There is a minor patch release every six weeks which coincides with "normal" Firefox version updates. All security patches are deployed to both release channels, but feature enhancements are not deployed to the ESR channel between major version releases..
