First of all, if you're not browsing the web with third party cookies disabled please stop reading and disable third party cookies for your own protection. Third party cookies (TPC for the remainder of this blog) are generally a bad thing. Don't believe me, listen to Security Now!

Unfortunately, you may have noticed that some of your extensions broke after disabling TPC. There are a number of extensions (add-ons) which require TPC but it's always safer to whitelist trusted sites than to try to blacklist all the bad ones. Here are some extensions which require TPC exceptions and the domain required for the exception. You should try to whitelist the most specific level domain (subdomain) where possible.
