 We've had several anecdotal reports that our TBB default of disabling 3rd
 party cookies breaks REcaptcha on some sites.

 It turns out there is a way to do REcaptcha without 3rd party cookies, but
 it is not the default mode. For example, drupal pre-6.x uses the 3rd-party
 cookie mechanism: http://drupal.org/node/1168740

 So, do we give up? Do we enable third party cookies? I think so, but
 perhaps we can convince Mozilla to update the patch for #3246 for us
 first, so we can try it out.

 If nothing happens on the Mozilla front, we should re-enable 3rd party
 cookies completely for TBB 2.2.x-stable and just rely on #523.
