Earlier quoted context omitted.
I said that in my first comment. You do a google search. The extension resolves every link on the page immediately via the goto urls. This doesn't leak any information to google because they obviously know which links they sent you. Now the links are resolved and you can copy and click them and get clean URLs, without sending any information about which ones you're copying or clicking.
Isn't that the same mechanism as the one you were saying it didn't need to use, though?
In my second comment?
I was replying to a detailed explanation of the old mechanism that ended with "that is no longer possible", so I said "it doesn't need to use that exact mechanism" referring to the old mechanism.
It needs to update to the new way things work. But that's fine. An extension that performs the same task is still fully possible.
