I checked Fox sports pages and I cannot see comments on some articles that I'm sure must have some with either browser on both Win 7 desktop and 8.1 tablet.

eg- http://www.foxsports.com/southwest/s...s-on-me-082014

does have comments.

http://www.foxsports.com/west/story/...ve-jobs-082014

Does not have any comments.

Both articles have been around for over 24 hours so I'm more than sure that they both would have had readers saying something, not just one of them.
