Hello

I am looking for a way to disable the QUIC protocol in Firefox by GPO. I got your latest AMDX templates but I don't see the option to modify network.http.http3.enabled.

Either an AMDX template with this option or a Registry will do the trick

Thanks

You can modify any network. preference value using the Preferences policy

Hello Mike

I followed that link but I am still not sure how to make it work. If you have any set of specific instructions that will be great

Thanks

Sure.

If you go to the Preferences section in the GPO editor, you can add this:

``` { 

 "network.http.http3.enable": {
   "Value": false,
   "Status": "default"
 }

} ```
