There is no organization. This is my personal computer at home.

Check the links anyway.

I'm 71 yo non-technical person. I don't understand what the links mean. Can you dumb down the instructions to a 6yo level so I can follow them step by step? Thanks

You can check the about:policies page (63+) to see if policies are active and if errors are reported.

• https://support.mozilla.org/en-US/kb/see-active-policies-firefox-enterprise

You can open "about:" pages via the location/address bar
this "about:" protocol is used to access special pages

You can inspect the Mozilla and Firefox keys with the Windows Registry Editor in HKEY_LOCAL_MACHINE and in HKEY_CURRENT_USER with the Windows Registry Editor to see whether GPO policy rules are active.

• HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\
• HKEY_CURRENT_USER\SOFTWARE\Policies\Mozilla\Firefox\

Note that the mere presence of the "Mozilla\Firefox\" key is sufficient to make Firefox display this notification, so if you have the Firefox key then remove it and only leave the Mozilla key or remove this key as well if it is empty.

• HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ =>
  HKEY_LOCAL_MACHINE\SOFTWARE\Policies\

All changes that you make in the registry editor are applied instantly, there is no UNDO possible. You can export key(s) in the registry editor before making changes. If you're not comfortable with editing the Windows registry then best is to skip editing registry keys.
