It seems to be Chrome trying to protect you. When I clicked the link (also in Chrome), I noticed a little silver shield show at the right of the address bar (next to the "favorite" star). Clicking that shield shows "this page is trying to load scripts from unauthenticated sources", with an option to "load unsafe scripts" or "learn more".

After I clicked "load unsafe scripts", it reloads the page and I can click the link. I'm assuming my system will explode, shortly.
