How to rollback to Firefox ESR v52.9.0 after automatic update.

I have been using Firefox ESR. I am not ready for Firefox Quantum because I want to use the legacy extensions "Show Parent Folder", "Go Parent Folder", and "Session Manager" and a few others. I am not concerned about security because I find Kaspersky Internet Security (and others) sufficient for my purposes.

So I downloaded file
firefox-52.9.0esr.win64.sdk.zip
from page
Directory Listing: /pub/firefox/releases/52.9.0esr/
but I don't know how to use it. I can't find a setup.exe -- or any .exe.

How can I roll back to ESR v52.9.0?

(I do have file "Firefox Setup 52.5.2esr64.exe", but that is apparently not the latest)

The latest Firefox Extended Support Release is 60.2.0:

Thanks, but I can't use v60.2.0. That is my current version that I want to replace with v52.9.0 in order to use my legacy extensions.

Hi,
What legacy extensions ?
I basically have one and it still works so it must not be a legacy thankfully :)

Anything which uses XUL - Wikipedia.

FIRST:
I installed Firefox Setup 52.9.0esr.exe and set Options to:
1 "Never check for updates (Not recommended: security risk)"
2 unchecked "[] use a background service to install updates."
3 In Kaspersky:
Off: "Software Updater" (it was already off)

Then the newly installed ERS v52.9.0 automatically updated to v60.2.0!

SECOND:
I repeated the above but this time I uninstalled v60.2.0 first.
I also unchecked "automatically update: search engines"

THIRD
Waiting to see what happens.
