We are running FF ESR 78.14.0. I see that ESR 91.1 is now out. I have seen this article on Firefox ESR release cycle, but not able to find out what the schedule is (ie overlap) for 78 and 91 releases. I am trying to do some upgrade planning. I expect 91.2 will auto upgrade and like to know how soon, otherwise I may need to manual update machines.

It would be nice if this page could be kept up to date for the relevant releases.

Driving the question is a specific issue with QuickBooks Payments not working in 78, which I am assuming has to do with something they consider obsolete security wise.

Chosen solution

There is always an overlap of two versions to make it possible for admin to prepare the new version and check for issues, so the last 78 ESR will be 78.15.0 along with 91.2.0 and the switch will happen with 91.3.0

Found this on Wikipedia which indicates 78.15 will be the last release on October 5, 2021 and that 91.2 will be released the same day.

I did a test upgrade and it cured my problem... moving on

Still would rather see this info here.

Yes, that's pretty much what I'm looking for, but Google did not get me there.

It should be linked here: https://support.mozilla.org/en-US/kb/firefox-esr-release-cycle Seems my link at the top is not correct.
