when I click on Apple TV on my Mac, the library window opens. How can I get to watch Apple TV content?

I was streaming Ted Lasso when the screen froze. So I Quit TV from the drop-down menu at upper left. Then when I clicked on the Apple TV icon on my navigation bar, the window that opened is a Library window, not a window that allows me to choose the next episode or any other content. I've tried going to https://tv.apple.com/ and I get a "Secure Connection Failed" screen. I'm using Firefox.

Thank you for your help! I took your suggestion and searched for Ted Lasso, found a link, and went on bingeing! It's just a mystery to me sometimes. Thanks again!
