1. Make sure you have the Social list enabled, update it
2. Go to http://rapgenius.com/Eminem-rap-god-lyrics
3. Click on a yellow line in the lyrics
4. In the overlay click on "Share"
5. A new overlay should appear
In Firefox this is working as expected. The overlay mentioned in #5 was hidden by ##.addthis_toolbox in the Social list. I fixed it with this whitelist rapgenius.com,tmz.com#@#.addthis_toolboxt but for some reason it doesn't work in Chrome. It also happens for me in the latest Opera stable release so I guess it's a Chromium bug.
