Hello,

I would like customize FF 66 via GPO templates but on some endpoints customization don't works. Gpresult on endpoint shows policy is applied, after policy applying I've got new registry keys in HKCU\Software\Policies\Mozilla\Firefox but Firefox seems don't see these settings. I try run gpupdate several times and restart endpont but no change.

Is in firefox any debug mode to show what is the cause? How to turn it on?

Thanks for all suggestions.

You will need to restart Firefox (and possibly restarting the system could help in this case) for the policy to be fully applied to Firefox.

If you go to the policies page (about:policies) on Firefox on the systems that are having issues, do you see the policies listed there?

There are also some helpful tips on logging and debugging policies in the Debugging policy issues document.

Hope this helps.

You have to add the policies to HKEY_LOCAL_MACHINE because HKEY_CURRENT_USER wouldn't make sense.

I don't add any registry keys by hand. When I run gpupdate applying policy automatically creates subkeys in HKEY_CURRENT_USER\SOFTWARE\Policies\Mozilla\Firefox.

I also try add poicy settings (for example for proxy) by others methods like policy.json and autoconfig but on some endpoints FF seems don't see these settings. I copy exactly the same files to different endpoints and on some of them policy work fine (so I except syntax mistakes) but as I said not on all.

Can I find somewhere more detailed logs with information what is the reason?

The Browser Console is the usual place to look for error messages, but if Firefox doesn't pick up the rules then there might not be error messages in the console.

You can check the about:policies#active page in Firefox 63+ to see what policies are active.
