User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0 Build ID: 20150812163655 Steps to reproduce: Since FF40 (could be unrelated), I am not able to login using yahoo After entering the email address, the pop-up displays 'Loading yahoo.com' but does not progress further. I have tried it on mozillians.org persona.org bugzilla.mozilla.org Here is an example of its URL: https://yahoo.login.persona.org/authentication?email=*******%40yahoo.com
Adding Dan and Gene for triage
FWIW, I tried using a yahoo email at persona.org, mozillians.org, bugzilla.mozilla.org and 123done.org, and could authenticate with persona, yahoo, and the Relying Party with Fx40.
Thank you Update: I tried again in Safe Mode and in fact it did manage to login. Therefore, it seems an addon might be the cause. I suspect, it could be NoScript or Ghostery as I cant think of any other addon that might have any bearing on the issue. I will do more testing.
