Why won't http://xfinity.comcast.net/ let me sign in using the newest version of Firefox? It worked yesterday, and it works with Chrome.

I have used Firefox for years. I have Comcast email. Yesterday, after the browser update, the following happened:

1) xfinity.comcast.net said, "Uh-oh, it looks like you're not signed in." 2) I signed in and the browser opened a tab that says "Kathy..signed in...My Account," etc. In other words, it looks like I'm signed in. 3) When I click on my email, I get a new tab that says, "Uh-oh, it looks like you're not signed in."

The only way I can read my email is to use Chrome. I'm unhappy about that. Is there anything I can try? Thanks, Kathy Boehm
