One reason for this probably is that more and more browsers like Firefox
save the tabs/windows state upon quit. If a user is logged in on two or
more Shibboleth-protected web pages that have configured a default
Identity Provider and they quit their browser, this state might be saved.
So, if they restart the browser, the browser opens the URL to these
Shibboleth-protected web pages that then redirect the user to the
default IdP's login page.
Therefore, the user ends up with two or more open tabs showing the IdP
login page. But - due to the reason Chad mentioned - only one of the
tabs will actually work after authentication succeeded. The other tabs
will end up with a "no context found" error message.
