I am an admin of some servers, i modify the proxy settings of firefox in a GPO, and it works, but now ont thing is that users can modify the settings of "No proxy for" in Connection Settings, then add the urls, then users can access to any web site which they want to, is there a method to disable this? thanks.

Assuming you have "Do not allow proxy settings to be changed" set to Enabled, you also need to Enable "Proxy Passthrough" and leave it blank and it will be locked.

You can create a 'policy'. I will post a link to a github page immediately after this post.

Hi Terry,

Thanks of your reply. My question is to disable the option of "No proxy for" via Firefox template GPO. then it does not work.

Have you locked the proxy settings? If those options aren't locked, that's a Firefox bug.

iI do only enable "Do not allow proxy settings to be changed" without enable "Proxy Passthrough", it works well after enable it.

Thanks Mike!
