I WANT YOU TO GIVE ME A SOLUTION NOT THE F'N COMMUNITY BOARD .

Hi Sonia, the "ImportEnterpriseRoots" policy instructs Firefox to trust certificates added to the Windows certificate store, not just the ones that Mozilla provides. It locks this checkbox on the Settings page to being checked:

"Allow Firefox to automatically trust third-party root certificates you install"

This article has more information: Automatically trust third-party root certificates.

But why does the policy exist? Unfortunately, there's no simple way to know what program created the policy, but usually it is added by your security software to facilitate intercepting and cleaning your browsing (otherwise, Firefox would reject its fake certificates).

If that is okay with you, then there's no need to remove the policy you found. But if that is NOT okay with you, then there are two possibly places that policy could have been added:

(1) Windows Registry (2) A policies.json file in a specific subfolder of your Firefox program folder

Do you want the steps to do the cleaning?
