I did the update to Firefox today. I am able to log into Comcast, but am having trouble with staying logged in. I go to the home page, it tells me I am not logged in, so I go to the log in page, log in, and it takes me back to the home page showing that I am logged in. When I try to go access my email, instead of taking me to that page, it just takes me back to the log in page. It also does this when I navigate anywhere else on the site. Help!
