Firefox shows the shield icon at the left end of the location/address bar in case content is blocked by Tracking Protection.

• click the shield icon for more detail and possibly disable the protection
• You can check the Web Console by Tracking Protection
• "3-bar" menu button or Tools -> Web Developer

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

• make sure your extensions and filters are updated to the latest version

Nice try. Disabled in shield. Only difference is then I did not see the comments at all. With enabled, they display for a micro second.

I had already tried with addons disabled. No difference. Rebooted, reloaded. There is something distinctly different, a recent change as this was not a problem a week ago. Can't say exactly when it started.

Still not working, and only on Firefox.

Try to enable third-party cookies temporarily to see if that makes a difference.

You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.

Clear the Cache and remove the Cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Remove the Cookies" from websites that cause problems:

• Options/Preferences -> Privacy & Security
  Cookies and Site Data -> Manage Data

"Clear the Cache":

• Options/Preferences -> Privacy & Security
  Cookies and Site Data -> Clear Data -> Cached Web Content: Clear

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

The site uses Facebook for its comments system, in case that sounds like it could be a factor. It's odd that they appear briefly and then... does that section go blank or does it close up/disappear?

They use facebook maybe for Foxinsider or FoxEntertainment but not Foxnews. The space closes.

More people are reporting the same issue - maybe you could contact Fox News Comments :

http://foxnewscomments.com/contact/

The comments should be in a #commenting container. but this container is empty in all cases I tried.

On another forum (about the same issue) somebody posted :

"Comments work for me at Fox News with Firefox, but only with Javascript enabled for the associated domains, of which there are a large number. So, if you are using the NoScript extension, try choosing "Allow all for this site". "

That's weird, the article comments look different today, and have the heading "Conversations". That section is embedded from an address on spot.im (screenshot attached). At least as of this viewing.

I use NoScript so it took a few "Temporarily allow all" and reload cycles, and patience while the site loaded for 30-45 seconds each time, to see the Conversations section.

Don't see it as a Foxnews problem since everything works as expected when using Edge or Chrome.

I do not use Noscript extension. I use some extensions but disabled them all and it still failed to show comments.

I don't know why you do not see the comments in your Firefox. Must be some setting or other factor we don't have in common.

FYI, Huffington Post also uses spot.im for "Conversations", and one of their readers reported a similar issue earlier today.
