Great extension that has served me well for a long time. Now that the functionality is available directly in Firefox (under Preferences), it has however outlived its purpose. Please remove the misleading "Recommended" badge.

This addon the best!

good addon, but now the functional is available from FF settings.

Fait très bien le boulot

Essential

This extension has become useless since Firefox has a build in option to do this since version 83.

This is now built right into Firefox, go into your Setting > General, scroll to the bottom > Network Settings and check 'Enable DNS over HTTPS' in proxy settings! Prior to that, had this installed. A+
-A very happy Firefox user

When i visit some pages like https://www.cyberciti.biz the memory is still growing and all tabs freeze. Firefox must be kill from task manager. I checked it with 85.0.1 with clear profile and nightly. The result is the same.
I search some options in firefox and i find that when i disable "Delete cookies and site data when Firefox is closed" all works perfect.
When i enable i have the problem.
