What is the live demo supposed to do? I just get stuck in an endless redirect loop with a counter going from 1 to 18 and then restarting. I’m using Safari on iOS.

Android/Firefox it showed me my unique ID after the first 18. Then there was a button to try again ans that put me in the same loop you're having.

FireFox for Android private browsing mode gets stuck in the loop 100% for me

This was fixed after we reported it a few years ago while working on the paper.

Safari on iOS. It goes to 18/18 and then starts over from 1/18 again for me too. I had not pressed any retry button, this happened the first time I visited the page. And I wasn’t even in private browsing mode. Just navigated to it normally.

Look at the Github repo:

- The last update was 2 years ago.

- It says that MS Edge 87 is affected. The current Version of Edge is 142.

This is no longer an issue, but it is interesting thinking about how long the NSA knew about this before the general population did.
