Adding insult to the injuries described in this post, Firefox prompted me today to “Connect with Mozilla”, even though I am already a member of most of the fora I have listed there, including Connect. Presumably this is due to each of these fora having separate registration and login mechanisms, despite their implementation of SSO via IAM.
Please complete the implementation of SSO via IAM, so that logging in once (in Firefox itself) logs one in to all of the sites implementing IAM.
