As for the Firefox release schedule: try the ESR. That does still release a new version every six weeks, but it's a "minor" or "micro" version, including only bugfix and/or security updates. The ESR resynchronizes to match the "rapid release" version once a year.
That's offtopic, though, so if further discussion is desired it should be done elsewhere.
