Since we've introduced the "other tools" tab, we've added quick links to open the current page in your favorite tool.
The icons you saw, were the favicons from these websites.
However one of these websites, the internet archive has been under a DDOS attack since a week, as a result the popup takes forever to open.
Our apologies, were are planning a big new release but that one isn't ready yet. So in the mean time a quick bugfix to help speed up the popup again.
