I know this question has been asked in the past, but I did not find a recent troubleshooting sequence that solved my problem. I have a Spectrum cable TV account (yes, I'm a dinosaur). MSNBC is part of my package. I like to stream videos of shows on msnbc.com. In order to access content, I have to sign in to my Spectrum account. When I click on "Please sign in", a box appears with various provider names. When I click on "Spectrum", the box closes but nothing else happens. I am not directed to the Spectrum log in page. I have cleared my cookies, enabled third party cookies, whitelisted the site on Adblocker, and am using Custom Content Blocking for Firefox. Nothing is working. Please help! Thanks.
