I am using Tor Browser 11.5.7 (based on Mozilla Firefox 91.13.0esr) (64-bit)

Earlier, when I browsed a site *in Tor Browser) which has a .onion counterpart, the browser would suggest, do you want to visit the .onion site or stay here (something like that). Now it is not doing that. 

What might be the reason? How can I get the early behavior?
