Firefox says there's an error in Comcast email and won't let me open it. I switch to Google Chrome and have no problem.

There have been issues reported with the idm.xfinity.com server and it appears that Comcast/Xfinity has forgotten to update/renew the certificate for this domain. You can contact Comcast and point them to the Qualys SSL Report for idm.xfinity.com.
