Disabling Firefox’s DNS Over HTTPS via Windows Group Policy

  1. Download Group Policy templates for your Firefox version here
  2. Copy *.admx files to C:\Windows\PolicyDefinitions
  3. Copy *.adml files to from en-US to C:\Windows\PolicyDefinitions\en-US (or other language folder if applicable and available)
  4. Launch gpedit.msc (gpedit.msc is not available on Home versions of Windows, if you have that, I recommend using third party Group Policy editor like PolicyPlus)
  5. Navigate to Computer Configuration -> Administrative Templates -> Mozilla -> Firefox -> DNS Over HTTPS
  6. “Enabled” -> Disabled; “Locked” -> Enabled.

Huawei B525 4G router: new firmware – no more changing DNS server manually?

Recently I upgraded my Huawei B525s-23a 4G router’s firmware (new software version 81.191.13.00.1134, Web UI version 81.100.31.02.1134) only to find out the trick to change DNS servers has stopped working:

No more DNS settings for you

After brief inspection with browser’s developer console, worry not, DNS settings are still here (hidden of course). To show the settings navigate to Router -> DHCP, press F12 and enter this into developer’s console:

$('#dhcp_dns').show();

Press enter, and the settings are back:

Change DNS server on your Huawei B525 again!

Tested with Firefox, Chrome and Chromium based Edge.
