user.js: OffTopic question: security.enterprise_roots.enabled does not work anymore in FF 87

I really struggled to post the question here since it does nothing to do directly with this project. But I also know here are a lot knowledgeable persons who might have an answer.

Until now I have used pref security.enterprise_roots.enabled = true to use OS certificate store in Firefox instead of Firefox internal. It seems that with the latest version, that is v87, this is not working anymore.

Does anyone know the solution?

Thank you in advance and wish you all best… cheers
