Hi,

We really encourage that you stay on the latest version to get the best browsing experience.

You are more than welcome to let us know if there's anything in particular that you would like to see improved or fixed with Firefox 89 update.

Thanks, I realise that you would prefer that I accepted the alterations. But some slight alteration you have made to the skin in the task bar search area makes the Tabs etc much more confusing. A small thing I know but I'm constantly irritated, so much so that I am tempted to try Opera - but I've been with Firefox a very long time, and use Thunderbird, so that would be a shame. To just tell me that I'm getting the best browsing experience doesn't help. Obvious subjectively my browsing experience before the download was better for me.

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

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