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

Thanks for the quick response and advice. This appears to have solved the primary issue with the annoying popups.

Steps: 1. Close Firefox. 2. Open the Registry Editor app. 3. Go to the following Registry key: HKEY_LOCAL_MACHINE\Software\Policies 4. Create a new subkey here named Mozilla (if nonexistent). You will get the path HKEY_LOCAL_MACHINE\Software\Policies\Mozilla. 5. Under the Mozilla key, create a new subkey Firefox (if nonexistent). You will get the path HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Firefox. 6. On the right, create a new 32-Bit DWORD value DisableAppUpdate.

   Note: Even if you are running 64-bit Windows you must still create a 32-bit DWORD value.

7. Set its value to 1.

You can open Firefox. The updates are now disabled. To undo the change, remove the DisableAppUpdate 32-bit DWORD value you have created, then restart Firefox.

Note that the current release is Firefox 90.0.2:

• Version 90.0.2, first offered to Release channel users on July 22, 2021

• https://www.mozilla.org/en-US/firefox/90.0.2/releasenotes/
• https://www.mozilla.org/security/known-vulnerabilities/firefox.html

Nothing works on a Mac. None of the proposed solutions work. Given the EXTREME number of problems I encountered from Mozilla, just to make this comment, it sounds like Mozilla will not allow you to turn off those annoying popups. December 2021
