Starting today, Netflix will not run on Firefox. At first I got an error message from Netflix saying to update Firefox, but it's already up to date. Now, the red "loading" circle goes around and around, but the show won't start AND the error message no longer appears. Netflix works fine on Chrome, but I'd rather be using Firefox.
