So as you know that in order to get a new Tor circuit, we have to first find it! It is buried under an area adjacent to security padlock and once you click on it, gotta again click on the “New Tor circuit for this site” option and this even does not look like a clickable object by design. It is very flat interface and unlike the “New Identity” button, has no straightforward visibility.
Not to mention that new users or any users unaware of this new design element in the address bar, won’t even know that there is an option to change the Tor nodes easily.
