Bonjour,

I deploy ESR 60.3.0 in my company. We need to make sure the DisableBuiltinPDFViewer is set to the default value 0 for application bahavior reason.

I set this value with a machine GPO, the reg key is correctly set, but the parameter is not enforced by the browser.

any help is warmly welcome

best regards,

Can you post the registry keys you created?

Do other policy keys you created work?

You can check the about:policies#active page to see if there are policies active.

I'm on ESR 60, I understand this feature is unavaible

This policy is supported in Firefox 60 ESR.

However if you want to disable this feature then its value needs to be false (don't know if '0' works).
