Displaying new comments in habratopics stopped working

Question

Habr

A few days ago, the display of new comments in habratopics stopped working. Previously, when I visited a topic that I had already visited, new comments were marked and it was not necessary to look for new ones to track the discussion. Now it has stopped working.

Is it something that broke for me or is this functionality disabled now for everyone?

Browser firefox-17.0, linux.

Answer 2
