Switching on DNS over HTTPS on various browsers

A new feature that is hitting all new modern web browsers is the ability to turn on DNS over HTTPS, which in my opinion is a very good idea - to keep the ISP snoopers off your traffic - so they have no idea where you are looking up or searching for. Not all Browsers have this facility at the moment - but I will cover those that do.

This by association is a recommendation for those that do.

Mozilla Firefox:

To turn this feature on in Firefox go to Preferences/Network/Settings and the just select the DNS over HTTPS as shown below.

Google Chrome Chromium:

To turn this feature on in Chrome or Chromium, open a new tab and type chrome://flags and in the search bar type dns and enter. The following will appear and just select enable for DNS over HTTPS


As this browser is based on Chromium you have to type opera://flags and then follow the above.

Microsoft Edge:

Again, this browser is based on Chromium, only this time just type edge://flags and then follow the above.

Apple Safari and Microsoft Internet Explorer:

I'm afraid at the time of writing the above two don't support it. Safari may well in the future, but I very much doubt Internet Explorer ever will.
