I just read the FAQ for Firefox "Total Cookie Protection" and I am sadly no closer to understanding what impact Total Cookie Protection has on how I should build web applications - I'm particularly interested in understanding how it impacts things like OAuth SSO support.mozilla.org/en-US/kb/t

@simon OAuth doesn't use third-party cookies so I believe it's all good. The problem is with SSO systems which use third-party cookies to transparently log you in across several domains.
