Firefox update message pop-up
I would like to know how to stop the Firefox pop-up update message that says "Update available. Download the latest version of Firefox". It's in my face all day long and very annoying plus it covers up the upper right corner of the screen. Please explain how to turn it off. Thanks, Phil Walen.
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.
