Hi, how are you? This time we’re going to talk a little bit about web browser security. In effect, there is a protocol called DNS over HTTPS that prevents the provider from spying on the websites you visit. Every time you try to access a website, the provider has to look up the IP address to access it. Often, we know the websites we visit and many ISPs do business with this information. However, even if they uses the HTTPS standard, the provider still has access to the website’s name and IP address. Therefore, what DoH does is encrypt the IP address using HTTPS. In other words, it hides the IP address that identifies each page, preventing it from being accessible to the provider. For that reason, let’s see how to activate DoH in Chrome, Firefox, and Edge.

How to activate DoH in Google Chrome

To use DoH in the Chrome browser, put this in the URL field:

chrome://flags

The advanced configuration options for Chrome will be displayed immediately. Please, inside the search engine enter DNS and then select Secure DNS Lookup. Then change the option to Enabled. Finally, restart the browser to set the changes.

Select Secure DNS Lookup. Then restart the browser.
Select Secure DNS Lookup. Then restart the browser.

How to activate DoH on Microsoft Edge

The new version of Microsoft Edge uses Chromium, which is the same engine as Chrome. Well, to enable this technology in this browser, please enter the following text in the navigation bar:

edge://flags/#dns-over-https 
Enable the DoH and restart the browser
Enable the DoH and restart the browser

Select the option highlighted in yellow. And in the menu on the right, enable DoH.

How to activate DoH in Mozilla Firefox

To activate this protocol in Mozilla Firefox it is necessary to enter the browser options. With this intention, please enter the following text in the navigation bar:

about:preferences

Once there, scroll down to the Network Settings.

Go to Firefox Networking Options
Go to Firefox Networking Options

A new window with all the network options will be displayed immediately. Please scroll down until you get to the DoH related option. Please check the box to enable it, and then select the DNS provider. Again, restart the browser to set the changes.

Conclusion

Ultimately we have seen how to enable DoH in Chrome, Edge, and Firefox. This way providers will not be able to know which web you visit. This represents a breakthrough in privacy and security. This is all for now before I say goodbye I invite you to see our post about how to free ram memory in Windows 10. Bye!
