Pinterest.com doesn't render properly
See this screenshot: https://www.dropbox.com/s/7f1zhqer2363mkt/Screenshot%202014-04-26%2022.37.40.png Note that it says "Whoops! Something went wrong. Try again." at the bottom; that shouldn't be there (in fact, there should be more pictures of watches there).
Also, lots of important-looking messages appear in the console; here are a few of them:

Disabling HTTPS Everywhere makes things work again.
