I'll try to "show" the issue but that is the problem, there is nothing to show. Here's an example. In Firefox go to https://www.foxnews.com/video/6348924731112 Clicking the "Arrow" on the video screen produces nothing ... no error ... nothing.

Now, use Chrome and go to https://www.foxnews.com/entertainment/reese-witherspoons-real-name-even-confuses-her-co-stars-oh-thats-right

Clicking the "Arrow" on the (same article) video screen causes it to run. Same for other browsers.

Am I misconfigured in Firefox somewhere?

It works for me. see screenshot You could post a full browser screenshot showing the page like mine. Did you try Firefox in Troubleshoot Mode?

Thanks for looking. I get that "image" too but the video does not run. I tried "Troubleshoot Mode" as you suggested allows the video to play. I guess this means one of my plugins/extensions must be the culprit.

I'll try disabling them and enabling one at a time to see if I can find the offending source.

It works if I click the permissions icon on the address bar and allow audio and video. See also "Tools -> Page Info -> Permissions"

It's apparently a permission thing. When I cut off UBlock the video plays, otherwise it does not work on Firefox.

Thank you all for your help.

Glad to hear you found the issue. Mark it as resolved and have a nice day if no further questions.
