I have benn using firefox for 20 years or more and this new update 89 is the most appalling update I have ever seen. How can I go back to the old version? I've tried uninstalling and re-installing an older version, but it won't let me. So I have installed the esr version, which seems ok, but I can't get my old profile back. Help please, I hate this new version.

Step one: How do you completely turn off update checks in Firefox v64? You can use a policies.json file to disable updates for all users. https://github.com/mozilla/policy-templates/blob/master/README.md or https://winaero.com/blog/disable-updates-firefox-63-above/

You can use a policies.json file in the distribution folder in the Firefox installation folder instead as also listed in the article, so no need to use GPO keys in the Windows Registry. • https://support.mozilla.org/en-US/kb/customizing-firefox-using-policiesjson ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

You can use the ManualAppUpdateOnly policy in Firefox 87+ to enable only manual updates e.g. via "Help -> About Firefox".

Note that it is important to stay up to date and install the latest security patches.

Step two: Note: Some versions of Quantum change how the data files are set up, so they may not be backward compatible.

If you still want to downgrade, look under; I still want to downgrade. Click the Directory of other versions and languages link. Look for the directory of the version that you want. But, remember that old versions may have security issues.
