Favoriting doesn't appear to work for me. When I click on the 'favorite' link on an article page, I am taken to my favorites page, and nothing is shown added to the list. I only see the message "To add a story here, click on its timestamp to go to its page, then click 'favorite' at the top."

Using Firefox 47.0 on Ubuntu 16.04. uBlock Origin shows "0 requests blocked".
