What is the official policy on supported releases for Firefox? I found a very old posting in this forum that seemed to indicate the current release and the previous release are officially supported?

Chosen solution

Official supported means that you run a Firefox version that receives security updates and that you run the latest available release as available via the download page, especially for ESR that only receives security updates.

Current Firefox release (93.0) in all languages and all operating systems here:

Current ESR release will change from 78.15.0 to ESR 91.3.0 with the next ESR release scheduled for later this week.

Interested in the policy on both FF and FF ESR. ESR is supported for a year; but does that require you to update to the most recent dot release (e.g. 91.2), or is all of 91.x supported?
